When people get it wrong, we call that a mistake. LLMs don't get the privilege of making mistakes, because there's no evidence of the idea required for something to even be a mistake. Can't call something unintended when there was no intention to begin with. (You absolutely can call it a mistake or unintended on the part of an operator -- I wouldn't say so of the LLM itself though.)
