No, I don't on my '04 Z16. Have your recently done any work on the air intake system? Have you checked for codes on the DIC?
Sometimes the rough idle might indicate a vacuum leak on the air intake or a dirty MAF which can be cleaned with an aerosol MAF specific cleaner.

Chased mine for a week before I found a vacuum hose leak at the PCV valve. Buy some carb cleaner and check all the obvious places.

First guess would be you might have a cam you odnt know about?
If it just started all the sudden and you have no codes i start looking for a vacuum leak, and clean your MAF
You could have a tuner local to you read your tune thats in the car now to see if anything has been changed.

I have noticed on mine at times. not frequent enough for me to worry about.like maybe 1 out of 10 use factor.
Feels like a mild cam. Also never any codes. I was told like you by GM it was a normal trait of the LS6
