What would compel a hadrosaur to evolve into an anteater?

It's not really a hadrosaur, it would stem from a line of basal iguanodont (on my world they're simply all referred to as 'Hadrosaurs') which had evolved a larger olfactory bulb. One lineage suffered insular isolation, eventually becoming an insectivore and after millions of years, it migrated back to the mainland during the last glacial maximum when sea levels were exceptionally low.
Realistically, I just haven't designed any small theropods that would fill the role and was just playing around with hadrosaur diversity although if that answer doesn't satisfy you, I am very eager for criticism!

Well, the thing is there was already a lineage of theropods pre-adapted to feeding on insects--the alvarezsaurs.

Ah I'm aware of those. I should probably clarify that this isn't based on Earth so not everything is completely parallel

Yeah, but it would probably be easier for a theropod to evolve into an ant eater than an ornithopod. Fewer intermediate steps.
