The issue is speed of deployment. Unless they basically sortied resources with the expectation it would be a rescue the moment it was reported missing, it won't arrive on time.
If this was a Navy sub as soon as it was confirmed that one was missing they would start positioning the rescue resources in the area even before it is located.
Yes, time is always the limiting factor in such rescue operations.
It’s still a good option for recovery operation to bring Titan to the surface, assuming it hasn’t leaked water into the chamber.
