They aren't wrong, though. At best, the sources cited by an LLM system would be a listing of the items used for RAG, or other external data sources that were merged into the prompt for the LLM. These items would ideally be appended to the response by a governing system around the LLM itself. I don't know of any major providers that do this right now. The median case is having the LLM itself generate the text for the citation section, in which case there really is no mechanism tying the content of a citation to the other content generated. IF you're lucky and within the bounds the LLM was trained on, then the citation may be relevant, but the links are generated by the same token prediction mechanism as the rest of the response.
