I mean, this is more-less what a student does when writing a paper, when they're forced to cite their sources. They first come up with an idea based on their own understanding/recollection, then they try to figure out where did they first took that idea from. If they remember a specific source, they'll cite that; if they don't (because there may not be one specific source they learned from), they'll search for some existing work that expresses the idea in question, and cite that.

I.e. in case of both the student and an LLM, correct citation doesn't actually mean the idea originates from the cited work - only that the work contains this idea.
