Maybe there's actually nothing Lina sees in Anna.
They probably met under cordial circumstances through an acquaintance. Lina felt bad for the new girl in town and took Anna under her wing. She didn't think Anna would be a long term commitment, or she assumed Anna was harmless and wouldn't be a big burden to invite places. But then Anna latched onto her and her friend group, and didn't bother to try to make any new friends.
And once Anna found out Lina was a Hadid, she wasn't going anywhere.
Lina is constantly posting on social media and calls everyone her BFF, so it probably meant nothing when she did it with Anna.
When Lina found out what kind of business Anna ran, she probably thought it was hilarious considering Anna had to latch onto her, and could afford nothing more than Louis Vuitton sneakers. She probably decided to watch how Anna was going to manage a career of lies, and when the tea started getting juicier, she wanted to fuel the fire by letting Anna use some of her clothing and living spaces.
Everyone knows that whatever is in the dark will eventually come into light, but she was just curious about how it would all go down and when.
Why not have some toxic fun until then?
She probably became close enough to Anna to where she developed sympathy for her, or even liked Anna. But Anna was so cringe that Lina only wanted to hang out with her when she was around Bassam and Kareem.
After the whole Instagram privatization and renaming drama, Lina and Kareem (and Bassam) realized that Anna's career became too volatile and cringey to be around. Lina is probably willing to go out to lunch alone with Anna if she begs and sends funeral flowers, but not invite her to intimate birthday get togethers where only your real friends are allowed.

I've had friends/acquaintances where we'd still hang out and get lunch with them because we'd been friends for 1-2 years, but their reputation was too bad to bring around "cool" people or friends who didn't like them/thought they were weird.
Sometimes, you had to make a decision on whether or not you should invite the friend to a party/go out, and at best suffer the embarrassment of having been acquainted with them, or just go out without telling them, having a good night, not posting about it, and possibly reaping their wrath later, or deliberately posting about it so they know that you no longer want them to sit with you.u
