I would say no; this is not a good or desired outcome, but it's not a "lie". The machine is not being deliberately deceptive in its errors -- it possesses no concept of "deliberate" or "deceit" and cannot wield them in any way.
Similarly, in the case of ChatGPT, I think this is either (a) more like a bug than a lie, or (b) it's OpenAI and the attendant humans lying, not ChatGPT.
