No! Why should the one receiving a generated answer when asking a person spend more effort validating it, then the person that asked the LLM the answer? They could have just replied: "I don't know. But I can ask what some LLM can generate, if you like."
Unsolicitedly answering someone with LLM generated blubbering is a sign of disrespect.
And sure, the LLM can generate lots of different sources. Even more than exist, or references to other sites, that where generated by LLMs or written by human authors that used LLMs, or researchers that wrote their papers with LLMs, or refer to other authors that used LLMs and so on and so forth.
The LLM or those LLM 'agents' cannot go outside, and do experiments, interview witnesses or do proper research. All they do is look for hearsay and confidently generate a string of nice sounding and maybe even convincing words full of conviction.
