My LLM use case preference is exactly that - a google replacement. I've modified my prompts to ask for links to direct source material, thereby allowing me to go deeper. I find this in no way different then a search engine.

The downside however, is that at least 50% of the links cited no longer exists. This points to a general issue with LLMs, temporal knowledge. I tend to at least go to archive.org on a per-link basis when so inclined.. But clearly that's not ideal.

Does anyone have a better solution, short of just asking the LLM to remove the extra step, and link to the archive.org cache for the ingestion date (which frankly, I also don't have faith in being accurate).
