This is no different than, say, the typical anecdote of a junior engineer dropping the database. Should the junior be held accountable? Of course not - it's the senior's fault for allowing that to happen at the first place. If the junior is held accountable, that would more be an indication of poor software engineering practices.

> More closely to the issue at hand this is assuming the “senior” dev isn’t just using an LLM as well and doesn’t know enough to critique the output.

This seems to miss the point of the analogy. A senior delegating to a junior is akin to me delegating to an LLM. Seniors have delegated to juniors long before LLMs were a twinkle in Karpathy's eye.
