Yes, I can make such a distinction - if what the LLM is producing is in the training data then it's not a "hallucination". Note that this is an entirely separate problem from whether the LLM is "correct". In other words, I'm treating the LLM as a Chronicler, summarizing and reproducing what others have previously written, rather than as a Historian trying to determine the underlying truth of what occurred.
