What is damaged?

So i was struck by a negligent motorist who is making my life a living hell at the moment, he hit me and caused some damage to my vehicle and his insurance is unwilling to pay the at moment (i only have liability (dumb i just learned))



Here are some pictures of the damage :

From the pictures it looks like the lower control arm dislodge from the ball bearing aside from that what other possible damage might this have caused?



Also do i need to take it to a specialist to get this damage fixed or are most body shops able to do this kind of work?



Thanks a million
