That's what I was wondering. I've never been interested enough to steal anyone else's code, but with all the code transformers and processing tools nowadays, I imagine it's trivial to translate source code into a functionally equivalent but stylistically unique version?
Assuming ML models are causal, then bits of GPL code that fall out of the model have to have the color GPL, because the only way they could've gotten there was to train the ML using GPL-colored bits. It seems to me like the answer here is pretty obvious, it doesn't really matter how you copy a work.
