Hi, Troy; An alignment will do nothing for the vibration, but should be done, anyway. It is 'possible' that a wheel weight was knocked off during the accident? I think that would be my first check. I would think that a broken belt in the tire would show up at lower speeds as well, but be sure to check for that, also.
I've never run into it myself, but have heard that a sloppy tie rod (inner or outer) can cause that symptom.
Good luck.
