I believe “VNM-utilitarianism” is problematic because it would suggest that it is a kind of utilitarianism. By the most usual definition of “utilitarianism” (a moral theory involving an ‘objective’ aggregative measure of value + utility-maximising decision theory) it is not.
However, I remember “VNM-rational” and “VNM-rationality” being accepted terminology.
