I would think the main use case for やる outside of punkish/rude/pet contexts would be more of a lighthearted put down sort of thing, in humor. Like, egging on your friend or something.
It is just listed as a * in it (the shorthand for it being ungrammatical). Generally, when I have asked natives about it, they generally say something like ないと sounds casual, and ならない sounds serious, so it sounds weird together.
