I can't say that I've ever seeing anything else besides FAMILY一族. Using the no particle would turn it into the Uchiha's family. It's a particle that indicates possessive or nominalizes verbs and adjectives, both isn't the case here.

And yes, instances where the ichizoku was omitted do exist. For example, here Sasuke says in the second bubble Uchiha no... kono ichizoku no me [...], which translates to The Uchiha's... that clan's eye [...].
