Do you think the LLM reads every page on the internet before generating your answer? Of course not. What happens is that it use some sort of ranking algorithm to pick the pages that are most likely to answer your query and reads *them* (at best. At worst it just makes something up). You aren't avoiding the problems with ranking algorithms by asking an LLM, you're taking all of those problems, adding more problems on top, and pretending that this is somehow better.
