You would have to disassemble most of the boat and xray and test parts to see if they were weakened by shear forces when the impact happened. There could be seriously weakened bolts and connectors all the way back to the prop. Also, since the Los Angeles Class build is over, there may be a lot of jigs and fixtures needed to manufacture major hull components that are no longer available.
My guess is that it would cost almost as much as a new Seawolf Class boat to repair her.

Not to mention the electrical and electronic components - particularly the reactor safety systems.
