As blockers are declared, any creature that’s tapped or affected by a spell or ability that says it can’t block doesn’t block. If there’s a cost associated with having the creature block, no player is forced to pay that cost, so it doesn’t block if that cost isn’t paid.

Lure doesn’t give any creatures the ability to block the target creature. It just forces those creatures that are already able to block the creature to do so.
