Really? I retain plenty of copyrighted material in my head. What matters is the contexts in which I reproduce it (if any).
A search index might also contain copyrighted material. As long as it's used for search queries as opposed to regurgitation there's no problem. Search indexes and LLMs are both clearly very beneficial tools to have access to.
