Dev never really said she was a rodent girl, he in fact only said people read her as ''some kind of'' talking and bipedal mouse, meaning she isn't really one. Her supposed rodent ears are just her bow as shown in multiple instances and that image that you use as proof only falls into the explanation he already gave us, that many people would read her as a bipedal mouse, and so that's the representation of that, their perspective. The joke is that she's constantly mistaken for a rodent due to her appearance and behaviour.
