Sorry to jump in, but I’ve noticed that while kids movies may or may not fall back on the good vs evil where evil dies at the end tropes, kids TV shows have definitely been branching out and exploring redemption arcs and featuring antagonists that are not actually necessarily bad/evil, but rather are just people with goals that run counter to those of the protagonists. Some notable ones are Steven Universe which features a group of very long lived aliens that have been in rebellion against their homeworld ever since they discovered that the Earth (which was to be destroyed for resources) had intelligent life living there. That’s a very very loose description of a fairly odd show but they make a point to demonstrate that every character has flaws and most of the villains either are redeemed and end up becoming allies or choose to continue with their mission because they honestly believe it to be the best/most moral course of action. The tv show (not the movie) Avatar the Last Airbender did a lot if that as well with very few villains dying, the worst becoming jailed after refusing to be redeemed but most legitimately having changes of heart that lead to their becoming allies as well. The sequel series Legend of Korra had more ambiguous characters and did a good job of demonstrating that every villain had a good reason for his/her actions and were generally doing what they considered to be “good” work. Sadly that show did have the principle villains either dying or being locked up at the end, but minor villains did convert and the show was plagued by production issues, which may have contributed to their choice to follow that plot line. All three of those, however, did not just have villains that weren’t completely evil, they had heroes that had definite faults and failings, which I tend to find just as important. I’m sure there are probably other shows out there at the moment that make similar choices, but my brother -who is an adult but is passionate about different forms of animation- was always obsessed with those ones so they are the ones I’m most familiar with. TV shows have the benefit of being able to have multiple antagonists, which probably gives them more freedom to explore different outcomes, similar to the way a show that has multiple female, LGBTQ or POC characters doesn’t have to worry as much about reinforcing negative stereotypes. If a show has only one named girl, for example, and the girl is weak, always in need of rescue and overly emotional at all times the character can be problematic, because that single character says something about an entire demographic of people. Put five female characters in the show and it isn’t an issue if one is weak, emotional and always in need of rescuing because then it is only making a statement about that particular character. Same with villains. If you have one villain and he or she is just completely evil and cannot be redeemed and must be killed at the end, that says something about enemies and how to deal with conflicts. If, however, there are many villains and one cannot be redeemed and dies at the end it’s less of a statement. At least that’s what it seems like to me.
As for movies, the comment above mentioned Lilo & Stitch which I think you would really appreciate. No one dies at the end. The monster created in a lab to be wholly and truly evil learns about love and family and is actually a protagonist. The people trying to catch the monster are the antagonists that take fairly extreme measures in order to “stop the evil monster” but eventually also learn about love and family. Another antagonist is a CPS agent bent on taking Lilo away from her sister… because he worries that her 19 year old sister cannot adequately care for Lilo alone and wants to make sure she is safe. The sisters want to stay together (and keep the monster) because they are family. There are definitely opposing forces but no one is truly evil, not the aliens, not the monster, not the CPS agent and not even the mad scientist who decided that creating an indestructible evil monster was a good idea. It’s a great movie. And it is available on Netflix.
