I don't care how it was prompted any more than I care about what exact thoughts went through your head before you realized it was a bug. The problem isn't usually a lack of information, but the abundance of non-information. Chatbots and the people who use them to pen bug reports frequently seem to have had "no time to make it shorter", as Blaise Pascal put it.
That you used an LLM to "confirm" the bug is an example of such non-information. The reproduction testcase and/or the reproduction steps and description of the expected outcome confirm the bug.
