Before you make any decisions make sure you get a proper diagnosis. Wiyh that you can make intelligent decisions on possible courses of action.
You’ve said a couple times you’re going to be dumping this car, so at this point it is simply a financial decision on return on investment (fix). If the motor is gone you’ll be in a tough spot...may be best to let it go as a roller since unlikely to recoup motor replacement costs.
sad to hear this...sincerly best of luck.

I have seen....
Over ported heads that cracked in the port.
Otherwise plain old cracked heads
Blown head gasket
Cracked block/sleeve. This is a dry sleeve so if the sleeve is cracked and coolant got in that way, the block behind the sleeve is cracked.
As stated, coolant can't come from a air to oil cooler.

I will be reporting back with what happened!

Thank you. I will definitely get a proper diagnosis done. Yeah, I'm trying to not make this massive loss for myself, but I also want to make sure the car gets properly taken care of (or just leave it and let a future buyer fix it how they want). There has to be a middle point somewhere.

I currently autocross at least once a month. I don't believe its hard on the motor unless you stay in 1st gear the whole run. And a whole day is about 15 (max) minutes of drive time which is less than one session on a track day.
The track can definitely be hard on the motor. Your car has the smaller oil capacity which can be a problem if the track you were on had long high G left hand turns which can cause oil starvation.

UPDATE: Got off the phone with the dealer. Turns out they didn't take the engine apart at all. Based on that and the fact that their current suspicion can't possibly be correct, I'm going to bring it elsewhere. I'm not sure I want them to tear down the motor now.

You may not get an answer and the situation may become somewhat uncomfortable, for them....

I asked them that, but I didn't press them too hard about it. They said they made the determination based on the state of the oil and the coolant. They said they'd need extra authorization from me to open the motor. Should I allow them to open the motor? I'm just afraid of having them touch it at this point.

You should post a thread in the SoCal regional forum and ask for referrals to a trusted shop.
Just an FYI, don't make any reference to having it fixed somewhere else and be careful of having them charge you storage. Also, you need to know how much you owe them at this point - just tell them you're trying to figure out what your finances need to be.
As for the condition of the motor: The poof and the dripping oil possibly suggest something more than a blown head gasket; but that is still possible. If the gasket totally broke at a critical point along the outer edge of the head, that could account for the coolant in the oil, the poof and the leak The fact that it turns over is good and that indicates the engine did not grenade and was not hydro-locked at that time. Ask if there is any indication of coolant/oil in the exhaust system.
Ask them where they think the oil is leaking from and what they think would have caused that leak.
What dealership is involved here?

I’d pull the car out now. I’ve got some pretty good experiences letting an incompetent shop do work only to end up triple paying for the same work/diagnoses. If your already uncomfortable and the forum is making more sense and providing more information just based on what you have described I’d go ahead and pull it. While Vette’s are definitely not a rare car, the LS7 is a unique motor and I think your finding out first hand that even most dealerships don’t have a ton of experience with the LS7. I think since AHP did your heads and your so close reaching out to Kohle is the best option. I’m sure they are busy but I’d image you could get them to expedite the tear down so you could know what exactly failed. Now while they may be able to get you a cause relatively soon, the fix could take a bit longer depending on what’s on their plate. My experience with AHP has been awesome and I’ll have more on them when I post my rebuild thread(it’s coming Kohle, just been busy at work lol) I can’t stress enough if you don’t have a warm and fuzzy feeling about the shop/dealership that has your car cut your losses and move on ASAP, otherwise you’ll be without a car for much longer and probably double pay if not triple pay by the time it’s all said and done. I’m hoping for the best for you bud, having gone through incompetent shops messing **** up and how much time and money I wasted I wish that upon no man! Good luck man!🇺🇸

OP, if your heads are intact, I'd look at one of Kohle's forged short blocks..but get your car over to him for proper diagnosis and tear down..

Thanks, 0H8Z06, assuming you hate these posts for the same reason I do.
There seems to be a disaster that has happened, but very vague information to digest. The poster has a sparse profile with no pictures of the car, and no location listed.
"should I just sell it as a roller". is a pretty catastrophic question to ask about your car. For those of us who own the same car, it would be nice see more detail. Pictures?

Agreed. That was just some dealership guy throwing out a WAG. Probably isn't even aware the ZR1 style oil cooler wasn't introduced to the LS7 until 2011.

I also keep little information in my profile on purpose. I'm a private person when it comes to posting on the internet. I've mentioned the area I live in (Southern California).
About the roller comment, I mentioned that because I didn't want to spend almost 20k on fixing the car only to sell it for low 30s when maybe I could save myself a ton of stress and sell as-is for 15 or maybe even more (meaning I would be out the same or less than if I would fix it).
The pictures I have won't tell much because no one has taken apart the motor yet. All I have are some pictures of some oil coming out of what looks like the air filter area of the car. If you or anyone else is interested, I could post those. I just didn't think they'd add any value. I also tried taking pictures of inside the coolant tank.

OP, thanks for providing info so far. I hope it's rebuild-able and a RCA is identified!

Sorry about the failure...I'm curious who the dealer is...FYI, you can buy a COMPLETE LS7 engine on line for $11k with NO tax and NO shipping...$19k is a real stretch

Thanks! I'm going to need it.
Sure, I'll post them. See below.
The squares show where the oil is when looking into the engine bay.
Seems like more is dripping in this area, the driver's side of the car.
You can see the oil going across the top of the rubber.
