To my knowledge, ornithischians were called that simply because their
pubes slant backwards alongside the ischia in a manner superficially
reminiscent of bird hips. Back in the early days of dinosaurology, there
were even suggestions that ornithischians had given rise to birds!
The name just became entrenched in the scientific vocabulary. Bakker,
for one, refers to use Predentata, a term coined by Marsh, as this
describes a feature no non-ornithischian has, i.e. a predentary bone.
