9-2 Penalties

3. If an opponent(s) of the thrower reaches through the throw-in boundary-line plane and touches or dislodged the ball while in possession of the thrower or being passed to a teammate outside the boundary line (as in 7-5-7), a technical foul shall be charged to the offender. No warning for delay is required. See 10-3-10 Penalty.

That tells us we can't call a T for contacting the ball through the throw-in plane since it wasn't in a thrower's hand nor was it being passed to a teammate out of bounds during an undesignated throw-in

All we can go on is 9-3-10

Art. 10...The opponent(s) of the thrower shall not have any part of his/her person through the inbounds side of the throw-in boundary-line plane until the ball has been released on a throw-in pass.
