I don't see any talking about agents "choosing" to go rogue, only agents actually going rogue. That is, behaving in a way different from what is expected or desired. Non-AI based software goes rogue in this sense all the time as well. It's just that AI-based systems seem to have the tendency to go rogue in more spectacular ways.

That said, software systems "choose" all the time anyway. They don't need to have some sort of anthropomorphic "will" to do this. They just need to be given the capacity to arbitrate between a number of options, even if that process is one hundred percent predetermined by the programmer ahead of time. There's no need to appeal to libertarian notions of free-will.
