Chop Blocks

You realize that a chop block does involve two players making a block? It is not a chop block if one player makes contact.

A chop block can be called by any official that sees it. In your case either the WH or the Umpire can call contact on the LB which involves the Center. Now if you mean a block below the waist, which is legal if the ball is in the FBZ. It is illegal if the contact is outside the FBZ.

Peace

Actually it is not legal to BBW any time the ball and block is in the FBZ.
Blocking below the waist - initial contact at or below the waist from the front or side and they are not the runner.
BBW is permitted in the FBZ when
1) by all players who are on the LOS and in the zone at the snap
2) the contact is in the zone
3) the ball is still in the zone
So if that LB was blitzing, he probably would have been on the LOS at the snap, so as long as the ball was in the zone, the block would have been legal.
