Here's David Fincher's take on Lisbeth:

There were discussions early on where people were like, She's a superhero!' And you go, 'No, she's not. Superheroes live in a world of good and evil, and she's far more complex than a superhero. She's been compromised. She's been subjugated. She's been marginalised. She's been swept into the gutter and she's had a part in it. She dresses like trash because she's someone who has been betraued and hurt so badly, by forces beyond her control, that she's just decided to be refuse. She can sit anywhere she wants on the bus, because nobody wants to deal with her.

Can't put Lisbeth in a box based on the notion of what we expect of male and female characters. That's the beauty of her character and why she is already iconic.
