Saving the ball by throwing it off an opposing player happens all the time. Where is the line crossed? Is it by certain body parts? If so would we then have to interpret if the player was throwing at some other part and accidentally hit them in an off limit part? So many questions.

I will say when I played back in highschool a teamate of mine was chasing a ball that was going backcourt after being tipped by two guys on the floor. He jumped in the air and threw it back at the guy laying on the ground in an effort to knock it off of him and out of bounds. The ball hit the player in the floor in the head. The official called him for a T then.

The line is with intent, IMO.

You are saying whether the intent was to hit them in the face? It would be ok to throw it off another part of the body such as the opponents legs even though they intended to hit them, correct?

Yes.

Questions, No Answers From Me ...
 

I was trying to dove tail throwing the ball at an opponent with the idea of a player holding the ball and pushing the opponent away with the ball, as discussed in an earlier thread. Are both of these, or either of these, or none of these, live ball "contact" in the sense that it's a personal foul, or are both of these, either of these, or none of these, live ball noncontact, and thus a technical foul?

I'm pretty sure that the throwing is live ball noncontact, and thus a technical foul. I'm not so sure about the "push", but I'm also leaning toward a live ball noncontact technical foul.

It would have been an unsporting technical. Not a flagrant foul.

I was thinking it could fall under 4-18-2. Of course, based on severity, whether the intent was deemed to be malicious, and the player's demeanor.
