Frozen II is a continuation of Frozen where Anna already had a love interest. Even then, the focus is not on the love story but on Elsa who remains forever single.
Live-action remakes don't count but the press for the movie is already trying to change the narrative that Ariel's dreams do not revolve around a man and he's more a bonus for her real goal of becoming human. The Snow White remake press is more telling where you have the lead actress outright criticizing the "outdated" prince and saying that there won't really be a love story in the remake, or love won't be a focus.
I don't watch the Marvel shows and I'm not really referencing them since they operate under their own label. You could throw in all the 20th Century movies or The Muppets with Kermit and Miss Piggy as examples then as well, but that's hardly the same.
Turning Red, besides being Pixar which is also separate and never had much of an emphasis on romance, features a little girl. I don't even think she's 13 in the movie and she had a crush but there was hardly a relationship. The crush was also on a guy much older than her, hence her mother's outrage. It's used as a comical storyline to precipitate her transformation into the red panda because of the stress of being embarrassed by her mother. If you call that a relationship, I'm afraid for you.
