I think it's more likely they want to call attention to the fact it was the result of agents, rather than shift blame.
I'm pretty sure everyone knows that OpenAI is liable for the software they create and run.
One of the main purposes of LLMs is to launder responsibility/culpability for (possibly nefarious) actions in the eyes of the public. The average person has no idea how LLMs actually work and think it’s plausible that an “agent” could go rogue without any human instruction. Terms like agent, thinking, reasoning, etc reinforce the misconception that the LLM has a mind of its own.

Are they? What legal consequences have they suffered?
