These ideas aren't mutually exclusive. You can blame a person for creating a rogue agent.
There was no rogue agent. That’s the whole point
What label do you prefer for the agent that did something it was not asked to do?
Person: "AI, please make me paperclips."
AI: "OK, I've now converted the entire planet into paperclips."
Alien observer #1: "Wow, that was a rogue AI!"
Alien observer #2: "False. We need to place the blame where it belongs, on the person who requested the paperclips."
Ultimately this type of terminology dispute has a tendency to miss the point.
