I gave it some more thought.

To all honesty this Lana girl creates hostile work environment. It’s something that might need to be addressed with HR. I’d first talk to her and mention how you feel about eye rolling etc And I’d bring up “hostile work environment”. If she doesn’t tone it down, go see whoever is the next chain of command or HR. Or perhaps go straight to HR.

I now recall that years ago I had a colleague who kept making sarcastic and uncalled for comments to me. The reason was that in order for me to do my job correctly, I needed him and other people do theirs: fill out a particular report or provide particular something for someone. He wouldn’t. But just not not doing it wasn’t enough for him, he started making nasty comments to me every time he saw me randomly not even if I asked him to do anything. One day I stopped him in hallway and calmly asked if he has some type problem with me because if he does that’s fine, we can then schedule a meeting wuth adminisyration and address it ASAP. If you don’t have a particular issue with me then I need you to stop these comments and other hostile behaviors forward me right now”. He got all red in face. He was in absolute shock. And just kept repeating “no no I don’t have any problems with you.”

He never ever did or said anything questionable to me and was polite and civil with me until he retired few years back

You might try something like that
