Linus's policy on patch acceptance covers the LLM problem: it must still be audited by a maintainer before acceptance (and thus, actually be decent code), but also, because of LLMs, be significantly produced by a human, as machine written code cannot be Copyrighted, thus, cannot be Open Source, and thus, cannot be in the kernel because it isn't open source.
Nobody is really against LLMs producing, for example, exploits for novel security bugs to assist security researchers in patching those bugs. The exploit itself does not need to be Copyrightable nor Open Source. Nor is anybody against LLMs accelerating debugging, and helping find the location and root cause of the bug; again, that is not producing the end product code, thus does not need to be Copyrightable nor Open Source.
