They are rare, but if you build a specific toilet targeted for people with disabilities (next to ordinary, simpler, smaller toilets) then you generally try to make it as accessible as you reasonably can and target a wide variety of different disabilities. Such toilets tend to have many adaptations e.g. different controls for faucets on the sink, different handling of toilet paper, different dimensions and spacing, etc.; and yes, for some people a button instead of a knob that needs to be turned is all the difference in the world, as they simply can't turn a knob. For a trivial (but not nearly the only) scenario imagine a person with prosthetic hands, or extremely limited grip strength caused by e.g. some cases of cerebral palsy.
