Jim Hill -- the ex-NFL player turned L.A. sports broadcasting legend -- has been hit with a restraining order after his girlfriend accused him of domestic violence.
It's all spelled out in court papers obtained by TMZ Sports ... in which Lori Lee -- who describes herself as Hill's "domestic partner" -- claims Hill got violent with her during a March 14 incident at their L.A. home.
In the docs, Lee claims she confronted Hill about a luggage tag on his golf bag from the Bellagio Hotel in Vegas. Lee claims Hill had told her he had been visiting his sister in Texas -- but it seems he was caught in a lie.
