Is the "shoeshine" BBW?

I know what you are looking for. The definition of a block is:
2.3.1.a. Blocking is obstructing an opponent by contacting him with
any part of the blocker’s body.

You are looking if the contact has to be active, and you are describing that the player just flops on the ground in front of someone and lets them run into him.
It is in my opinion very much a block, and since the initial contact is below the waist, it is a block below the waist.
The O lineman knows that the defender will be moving in that direction - and is actively trying to prevent it with his body.

We had a similar problem with our flag football. There was no blocking beyond the LOS, so team mates would run in front of the ball carrier and 'place their body' in front of a defender so that they couldn't get to the ball carrier.
Technically the rules used defined blocking as the use of hands to push an opponent, so some coaches thought they were smart and it didn't conform to blocking.
We just gave them 15 yard illegal contact fouls instead (which it was).
