Lindsay has severe mommy AND daddy issues....
so I'd say she laps up the attention and love from any gender that bestows it on her
I don't think its remotely about being gay or straight or even bi for her. I think her hook ups are about her significant emotional problems.
Not that I'm a Hohan expert, but I tend to think she's an extremely promiscuous young woman who likes to experiment. So no, I don't consider her a lez per se.
