Looks like a big SUV hit you. Makes me sad that we're equipping worse and worse drivers with larger and larger vehicles in a dumb arms race.
The Niro's unibody can take a hit. I purchased a totaled one at an auction - I was specifically looking for the PHEV.
Fixing up accident damaged cars is not something the typical mechanic shop is going to do for you. It's for hobbyists, DIYers, body shops and insurance companies. Some states will give you a hard time trying to put it back on the road if its title has been wholly or partially condemned (salvaged, totaled, etc.) by the insurance company.
A competent body shop can do an evaluation for a couple hundred dollars, provided you give them the car with mangled panels and components removed. You'd need to be good at looking through parts diagrams and will need a cooperative Kia dealer to help you with this. If the air bags went off you'll need to figure out the costs of resetting the system and replacing those (it can be a lot, and a Kia dealer will most likely have to do this).
The Niro's body is pretty bendable - what is out of alignment can be bent back so long as nothing structural is cracked.
Mine took a hit on the front right corner - you can see the red paint on the bumper area. I picked this one because the hit was minor. The front cage took all of the damage and went about 1.5" to 2" out of alignment.
The insurance company estimated over $8,000 in repairs but elected to send it to auction instead of having it repaired. I put under $2,500 in parts and expenses into it. I had a local body shop put the car on the frame machine and bend it back into alignment. I had them paint the new front bumper cover, which came unfinished. I scoured all the parts from diagrams I got from a Kia dealer and got everything I needed except two plastic clips (the diagrams can be hard to tell which parts come in sets and what come alone). It took me about three months to get it together, titled by my state, insured and registered (as a "rebuilt title" that is pretty much only good in my state - most states will not honor another states rebuilt car because many will not even allow them back on the road like Maine will). Insurance is a wild card too. I had to shop around and couldn't get comprehensive coverage.
