courts assert LLM can't HOLD copyright, as in it is not an entity that can own something and go to court over such ownership
nothing is said about you the user holding copyright over result of tool use

"Given this framework, it follows that purely AI-generated outputs—those created automatically by an AI system without substantial human intervention—are not eligible for copyright protection in the EU. Such outputs are considered to fall into the public domain, making them freely available for anyone to use, reproduce, or adapt without seeking permission or providing attribution. The legal and commercial implications of this are significant. For creators and companies investing in AI systems that generate music, art, or text, there is no proprietary right over the final output unless a human has contributed in a way that meets the “intellectual creation” standard."

The courts are AFAICT still undecided in the US regarding this.

"...prompts alone do not provide sufficient human control to make users of an AI system the authors of the output." [https://www.congress.gov/crs_external_products/LSB/PDF/LSB10...]
If code generated by LLMs turns out to be effectively public domain, that could seriously water down the legal standing of copyleft licenses. Fortunately there is still enough human-authored code that long-standing projects as a whole are not at risk of losing all copyright control, but as more LLM-generated code is incorporated, and human authored code is deleted, the copyright slowly gets washed away.
Having said that, I suspect the big AI companies have enough lobbying power to influence the legal system and lawmaking in the future.
That to me is the reason not to accept LLM generated code, at least till the legal copyright aspects are better regulated, because for now it exposes to too much risks.
