You and your team will have to decide, but in my experience generating commit messages is not particularly useful.
Because you really just want a short (ideally one-line) summary of the changes. If someone's interested in the details, they can look at the diff (and hell, have that then summarized by an LLM, if needed). Adding a bullet point list for each concrete change adds a ton of noise to the commit log, which is IMHO not worth it.
Where long commit messages are actually useful is for documenting things that aren't written into the code, mainly why you made the change. But since they're not in the code, the LLM can't generate that part for you.
