As agents become more and more powerful, it would be good to get clear legislation or precedent in place that makes either model creators (OpenAI) or operators (whoever is running the model) liable for their agents' actions.

I kind of agree with them, in this case both parties essentially settled it between for PR reasons, but what if the attacked party actually was damaged. This is as if two friends got into a car accident and decided to not get police involved, the one who caused the accident should definitely get punished either way. Goal is to prevent future "accidents" with the punishment not to punish for punishing sake.
