That actually looks like it could be saved. The front tire doesn't appear off camber or anything, so there shouldn't be any mechanical damage other than the radiator.
Your best bet may be to just take the car back and walk away without a settlement. The car should keep a clean title that way, and not be declared salvage. I don't know what the law is like in Oregon, but here in Alberta, once a vehicle gets branded as salvage it's extremely difficult and expensive to get it back on the road. Plus, that branded title makes future resale more difficult, if you ever wanted to sell it.
