Boeing doesn't give Uncle Sam a discount because a LEGO project pays them money. If they do work for the military, they will bill it directly to Uncle Sam.
I doubt the amount of money even matters to them. It's most likely linked to retaining their trademark or something similar.
Finally, the V-22 isn't an attack craft. All experiments into the idea have been outright rejected and the only weapon it carries is a single browning machine gun which is optional (and could easily be mounted to basically anything). This is like protesting the creation of a truck model because technicals exist.
