Yeah. The anime community has a lot of debate on these things. I guess it makes sense that not everyone is on the same page with regards to the eternal flame wars / arguments here.
Avatar, Star Wars, even Boondocks comes up.
I think My Adventures with Superman was Korean at least, but stylistically it's close to anime.

The one people may have forgotten about is RWBY, which was the famous Texas Anime (erm... Texas made anime-inspired art?) that split so many people with debates on 'Anime or Not'.
"The famous Texas anime" is King of the Hill. People in Japan argue over whether watching it is better with subs or dubs. It's a slice of life anime in all but drawing style and origin.
Rather than "if", here's two instances of that idea I know of:

Edit: And it actually looks like some anime studios did get in on Star Wars: https://en.wikipedia.org/wiki/Star_Wars:_Visions
