A real life Leni would be bullied into depression and cynicism (which by then she wouldn't be Leni anymore, she'd be a sad mutated thing that was once Leni) by other girls and become sad and bitter before she's even done with middle school, because kids are assholes and being stupid, vulnerable, and harmless is an invitation to get bullied. Alternatively, a theoretical real life Leni could be extremely sheltered and stay that way into adulthood, but then you'll never meet her because people sheltered like that are controlled by their parents who would smother her and prevent her from meeting anyone they might not approve of.
In short, Leni can't fit in with other girls. She wouldn't want to be the way she is because she has an ego of her own that needs to be satisfied and being dumb, harmless, and vulnerable and being aware that you are those things isn't something girls would want, they generally wish to be independent and strong. And even if she was this way, she'd be sheltered and you wouldn't be allowed to date her because you're not on her smothering daddy's "Nice" list. Leni is a cartoon character. She cannot exist in the real world. She has no place in this world.
