There is no way to reliably identify code as AI-generated, unless it is explicitly labelled so. Good code produced by AI is not different from the good code produced by software engineer, so copyright is the last thing I would be worried about. Especially given the fact that reviewing all pull requests is substantial curation work on the side of maintainers: even if submitted code is not copyrightable, the final product is.
