US State Attorney Generals could step in and charge Lego for bait and switch violations and/or false advertising. Which could be big time financial penalties applied. That said, where did Lego say OUTSIDE the instructions that these minifigures were exclusive. An Attorney General is going to need to see the fine print was visible to buyers in advertising and/or product listing. If this "exclusive" note was inside the box requiring people to buy the set first and then see the exclusivity note, I'm not convinced the AG is going to see a legal case. I realize that "rumors" would start flying as soon as the set was purchased and the initial buyers saw the exclusive note but can you direct us to where Lego claimed they were exclusive in a way buyers could see this fact before they made a decision. Pardon the fine legal line I'm drawing here.
