I do. I'm torn, actually.

On the one hand, if the defender attempts to kick the ball and misses only to succeed immediately after, it sure seems like it should be a kick. I mean, the defense was trying to get the kick, to be honest.
OTOH, if the offense throws it at her leg purposefully to get out of a jam, it seems a bit unfair to go with the kick.
My read on the OP, though, doesn't involve this. I see it as a player jumping and extending to block the passing lanes, knowing full well that the offensive player will probably throw where her legs are going. She swung her leg with the intent of kicking it, the player faked the throw, and then released it prior to B1 landing. B1's initial attempt at a kick is successful. I think I'm with MTD on this, if her feet hit the floor first, I'm letting it go. If her feet hit the ball prior to touching the floor, it's probably a kick.

However, it's definitely a "had-to-be-there" play.
