Shouldn’t need an llm to check. It’s just a list of authors. I wouldn’t trust an llm on this, and even if they were perfect that’s a lot of resource use just to do something traditional code could do.
I would assume you would use the LLM to not only check the source exists but check that the citation referenced actually says what the author says it does. That's not something you can do heuristically, I would think.
