2011 Toyota Camry engine problems

I was driving east on secondary road when a driver failed to stop and hit my car; first impact hit at my drivers side at front left of car then also she hit the left back side of my car which swung around at impact. Driver stated she didn't see my car. She was ticketed at fault and both of us were transported to hospital. My car's airbags did not deploy at all, not even the side impact bags!

While traveling on route 78 west near bethlehem pa the oil light began to flicker. We pulled off the highway into a GM dealership. The mechanic said the oil was leaking out the oil filter and there was no oil on the dipstick. Now the engine is making a grinding sound when it is starting and other sounds. I'm afraid that we will have to be replaced the engine or the car. We have 3 years left on the car loan. The oil and filter were replaced 32,012 at sears. I have saved the failed oil filter.
