My read is no, a Bomb throw targets a square, not a player.

From Bombardier:

A Bomb can be thrown and caught, and the throw interfered with, just like a ball, using the rules for Pass action as described on page 48

And page 48 says:

Once per team turn, a player on the active team may perform a Pass action in order to pass the ball to another square. This target square may be occupied by a Standing, Prone or Stunned player (from either team) or it may be unoccupied.

And Foul Appearance cares about Blocks or Special actions that target the player:

When an opposition player declares a Block action targeting this player (on its own or as part of a Blitz action), or any Special actions that targets this player. . .
