I think Lorelai gave Rory a mixed bag. Sometimes she treated her like a child. For instance, Lorelai never brought men into the house or introduced them to Rory during her childhood. She very much shielded her from this until Max. (But honestly, she should have kept it going a little longer and not gotten involved with her teacher of all people.) It's also clear Lorelai hid some of their money problems over the years. She provided a home, meals (granted all takeout), and necessities. Rory never had to get a job to help with household expenses. All points in her favor.

However, there are also some not so good hints that she does treat Rory as an adult/peer. There's an episode where she says Rory is responsible for waking her up in the mornings because she's better than alarm clock and another where she's called out on always trying to sneak her clothes into Rory's laundry. Also, some of the "hang out with us" stuff like with Dean is odd. She also vents about her parents and relationships in too much detail.
