I had a similar situation with a chatbot: I posted a highly technical question, got a very fast reply with mostly correct data. Asked a follow-up question, got a precise reply. Asked to clarify something, got a human-written message (all lowercase, very short, so easy to distinguish from the previous LLM answers).

Unfortunately, the human behind it was not technically-savvy enough to clarify a point, so I had to either accept the LLM response, or quit trying. But at least it saved me the time from trying to explain to a level 1 support person that I knew exactly what I was asking about.
