thats what i got as well, it was meant to show how innocent she was.......I tend to be sensitive to this sort of thing, but this wasn't AT ALL what I got from that scene. The orange and chocolate stuff seemed meant to show that Alita is very childlike and hasn't enjoyed a lot of experiences that are normal on earth, like eating something sugary. It wasn't like she associated chocolate with the guy, since she also asked her father figure if he had any chocolate. She just liked the taste. Tons of people do -- it doesn't have to be something sinister.
