You sound very lovely, nona. I'm always happy to help shed positive light on the lore! You're reading on the univer.leagueoflegends site, right? Just making sure you're getting all the delicious morsels of story you can.
My favorites are basically completely opposite of yours lol! I enjoy the villain types with strong wills and larger than life passion for whatever is motivating them. Jhin, Viego, and Thresh come to mind first. Gwen and Lillia are both great characters so please don't worry about who might be most loved or hated! The roster is large and much of the community is jaded as it is, like, they take characters/lore for granted whether they're objectively good or not. 75% of the playerbase doesn't have any right to say shit about the lore imho kek. Anyway, let me get to the recommendations.
Amumu, Ivern (can also fit hippie vibes), Kog'Maw, and Kindred (best written char in the game next to Jhin imho).
>hippie kinda stuff
Maokai (can also fit creepy/cute/spooky), Lulu, Neeko, Nidalee
>strong feminine characters
Senna (can fit spooky), Akali, Illaoi, Karma (might fit hippie vibes), Miss Fortune, Samira… to be quite honest, most of the women in this game can fit here so I just gave you recs that came to mind first!
I hope this helps you get started and if you have any more questions or want to just talk more please let me know.
