Not necessarily. Inside front tire wear is very common on high performance cars such as the GTO and Vette. I see posts like this several times a week on the vette forums.
I don't know the stock GTO alignment specs, but for the Z06, the stock front camber (nominal) is -0.7 and front toe (nominal) is 0.08 degrees (out), though there is a pretty big tolerance on each of these specs. I suspect the GTO is the same. Negative front camber really helps handling. On the track, I am running nearly -3.0 degrees of front camber. Downside to the front negative camber, particularly with toe out (or in), is that it drags the inner edge of the tire along the road when driving straight.
To correct this, I suggest you find the exact GTO alignment specs (maybe someone with a service manual can post them), and get an alignment with front camber within specs but near the low end (less negative) and front toe as near zero as allowed. You will lose a little performance this way, but gain tire wear.
