FOSS isn't entirely immune to AI mania (or rather, LLM mania, because no 'intelligence' is inside).
I think LLMs can tentatively be used for some useful things, like checking for security bugs in new kernel code. But this does not answer the difficult question whether it should be used, because there are many important points in contra. Apart from massive pollution of the biosphere, it causes also a kind of pollution of collective knowledge and understanding. Which is a very important aspect of FOSS, and one of the things which bring us together.
For example, as Joey Hess wrote, if a distribution's package build code is done by LLMs, it is likely to become harder to understand over time. This is probably not the kind of technical debt which a distribution with limited resources wants to have. And you see, the decisions of individuals affect other people too, which is why we have rules.
