I'm sorry you had a bad accident, I'm glad your ok! Your vehicle can be replaced, and it most likely will. From the picture it looks like the frame rail that I can see is buckled, most likely the other side has some bend to it also. I don't believe there are any aftermarket parts available for your vehicle, and they would not use them on a vehicle this new any way.
I do believe your done! Totaled!
Minimum state coverage may vary from state to state, the last state I had to use my underinsured motorist was 5k property damage for state minimum coverage. So, most likely your insurance co will be paying out to you, and collecting whatever they can from the at fault drivers insurance co.
P.S. Stop worrying about what if this, what if that! If you insurance co took your vehicle to their salvage yard, that's a big sign! Just sit back and relax for now.
