The above provides the context.
To me, Miss Fortune doesn't quite fit the trope since she's not really heroic; she's at best an anti-hero. And Evelynn? Not even close. Pure evil.
Ahri on the other hand? Hard to tell.
I don't think so. Ahri doesn't seduce people in her lore, and when she does prey on people it definitely isn't heroic, but purely selfish.
What they said: Ahri kind of fits the seductress part, to a lesser degree than other examples, but pretty much fails the heroic requirement. She's never been involved in major events and has shown no desire to change that. Xayah calls her a traitor for not getting involved, and Irelia complains that she should stop fooling around and help fight in-game. She may end up getting more involved if they ever continue her story, but at the moment she doesn't really fit any kind of heroic anything.
