Considering how terrible the original novel was, Ibelin is 100% a mary-sue.
I think that since she is so beautiful and talented - and almost everyone else is ugly - she never had to work hard to get attention. Everyone falls for her looks and try their hardest to please her. Like with that terrible play she made the fishes watch with her. It was something only she could find interesting and she doesn't seem to realize that.
I think that usually she just doesn't bother to do her best. Maybe the reason Latte remembered Ibelin being a bad dancer was because Ibelin used that as an excuse in the original novel to not dance with the fishes and keep reading her books instead.
But once she noticed Armin (and Latte) breaking out of her spell and losing interest in her she had to do something to keep his eyes on her. So she actually started using her skills - which are many, since she is so OP. But it wasn't enough. Armin kept bothering Latte. And now she is starting to see Latte as an obstacle.
Of course, I may be mistaken.
Regardless I agree with you on the point that Ibelin is dangerous and Latte should be more careful around her. She already tried to push Peridot's ridiculous trap on Latte. And now that Armin pretty much showed Ibelin that he is interested in Latte I'm afraid Ibelin will try to get rid of her somehow. Or team up with Peridot, since she has a crush on Armin.
Nah, Rey is OP but not a mary-sue. Otherwise both Finn and Poe would have a crush on her. Mary-sues are super attractive, can do ANYTHING well and are loved by everyone.

I bet your ass she did v.v* girls that day an age love status but you know I'm rereading it now and i can totally see how different she is with him. I never noticed before because I always just thought he was funny. But shit lowkey I'd totally want the magician boy out of the three to. Cuz he is soooooooo fine!!! Because yeah the prince is childish and the Duke is kinda meh.
I think ibelin might be a reincarnated person like latte cause latte remembered reading about ibelin is not good at dancing but somehow is good at dancing in the story (chapter 45) . She's really dangerous and mysterious makes me kinda scared of her. Hope latte stop getting close to ibelin
