Sounds like starter to me?
How fresh is the battery? Cables all tight?

Sounds like the starter solenoid clicking. Many times the starter is bad but it may be loose battery or starter cables.

Sounds like a pretty solid knock, more than just the solenoid. Almost like the bendix is hitting the flex plate instead of engaging and allowing the starter to turn.

Can you get a socket on the front of the crank and give it a little movement in either direction and try to start it again?

Maybe just try to turn the engine by using the serp. belt. You shouldn't have to move it very far, just enough to let the starter engage.

Charge your battery up real good then try it
If it keeps doing it replace the starter.

Disconnect the battery first when you do it.
2 bolts it drops down. There are some wires attached so dont let it rip them out. Easy repair

That could mean a few things:

damaged flex plate outer ring gear
damaged starter drive gear
damaged bendix
solenoid getting ready to go down for the count

Does this happen often? Does the starter grind at times?

Starter under the motor passenger side. Behind the exhaust manifold.
Maybe someone has a diagram or photo of theirs, dont have a vette.

At least you know that you can get it to start if you have to, but probably gonna need a starter/solenoid replacement. Got any mechanically inclined friends that will work for beer?

If you are happy enough with them working on your car, I would let them select the starter.

A very common problem with the Nippondenso starter
are the 2 copper battery lugs and the copper disc
on the solenoid plunger pit and make poor contact.

You can purchase them for around $20.00 on Ebay Motors.
Search for 94 Corvette starter solenoid.

Here's a video describing the repair.
