Ocean apparently said Ayua is a different case. That means she's important to the story in a way we don't know yet. Ocean hasn't revealed whether she is or isn't, but at the time the list of LI's was put together, that was the best knowledge people had. Ocean rendering her dressing provocatively when Marla was doing the same thing certainly suggests her wardrobe choices (and the fact she is super interesting in Nika's dick in so many scenes - asking Bella for pics, staring at his crotch with Sasha, asking about it in the locker room etc) are because she wants to find out what's in NIka's pants. I can also imagine her at least being lewdable with drunken one night stands.
Maja is in a different situation - she will apparently be lewdable, but no romance, because she won't break Vic's heart over a guy. She used to be a LI when Ocean started writing, but her character is to put Vic's happiness first. But lewdable - you really think Ocean mentions she's into bondage, and she has a large collection of toys and she's not going to do anything? We'll get something spicy one night in a moment of bad decision making or drunken one night stand I'm sure.
Sounds like I'm repeating myself with the drunken bits, but Maja thinks Nika needs loosening up with alcohol, so buys a bottle for Vic, and Ayua gets very handsy when drunk.
