Yes. You penalize the complete act.

There are 3 different illegal acts by a defender on throw-ins:
1) Reaching through the plane without contact. The penalty is a warning the first time, followed by a "T" for subsequent occurrences. Rule 9-2PENALTIES(Art.10)1 & 2.
2) Reaching through the plane and contacting the ball. The penalty is a technical foul charged to the defender. Rule 9-2PENALTIES(Art.10)3.
3) Reaching through the plane and contacting the thrower.The penalty is a an intentional personal foul charged to the defender. Rule 9-2PENALTIES(Art.10)4.

Don't read anything into the play that isn't there.

The only exception(5 seconds or less remaining in the game) is listed in case book play 9.2.10.
