The dealership understandably doesn't want to risk a rejection and the potential reputation loss with GM.
As you see from my sig, I've done the same, we rolled the dice by not getting a ZL1, and if it's an unlucky one, we implicitly agreed to take the loss. Just my 2 cents'.

So far it’s just one dealership that doesn’t want to play ball, one other dealership is at least trying and putting in a request. You cracked a crankshaft as well? I get the whole mantra of yeah it’s a supercharged car, but when you have multiple GM techs, independent mechanics, and input from other mechanics from different shops that it’s almost impossible for this crack to have come from anything other than a factory defect, it’s decent grounds for a warranty claim.
Had it been literally anything else, such as the rod coming loose and smacking into the crankshaft somehow, I’d have no arguments and would accept it. But when it’s a situation of literally everything else is in perfect condition with no issues (all rods, pistons, rings, etc) besides the two bearings where the crack is, it’s pretty compelling in our opinion
