I think it easiest view this usage of "animated films" as a genre rather than an a technical description. Films like the MCU and Avatar will have digital effects on every frame but they are not marketed as animated films.
According to Wikipedia the top 5 are:
- Despicable Me
- Shrek
- Toy Story
- Ice Age
- Frozen
For some reason Wikipedia isn't listing Pokemon on the animated franchise table but The Numbers put the Pokemon franchise box office at $1.156b. If we cross reference that with the Wikipedia table that places it above The Lego Move but below The Secret Life of Pets.

I think this might be missing a few line breaks.
