Utilitarianism uses a version of global utility that is based on summing individual utilities.
If you could show that some notion of rights emerges from summation of individual utility, that would be a remarkable result, effectively resolving the Trolley problem.
OTOH, there is a loose sense in which rules have some kind of distributed utility, but if that not based on summation of individual utilities, you are talking about something that isn’t utilitarianism, as usually defined.
