Yes, but you're talking about aggressive, not passive aggressive. Passive aggressive can also be hostile, and both Bella and Sally (among others) start out as the perfect examples of that.
You can argue over the meaning of the English words all you like, but the bottom line is that the concept of tsuntsun which those words are trying to translate and to which the tsun in tsundere refers to very much includes being aggressive. This is the origin of the term. Today the original concept of tsundere has been divided into multiple terms with more specific meanings and the term is most commonly used for a character that goes from aggressive to loving and the aggression is typically fuelled by embarrassment over romantic feelings. A typical tsundere girl will hit a guy to punish him for making her fall for him and the more she likes him the harder she hits until she calms down and accepts being in love. Being embarrassed is the key. Sally and Bella don't do that. They are nasty to MC because they don't like him and get friendlier as he wins them over. Tsundere might still be the best way to describe Sally, but she is not a typical one.
A tsundere will initially resist their emotions out of irrational fears for being embarrassed, looking stupid or being made fun of. Sally definitely does pretend to understand chemistry exactly for those reasons so you can easily imagine her doing that because she is falling for MC, but there's no real indication of her having those emotions until ep 11 when she is already softening up and her behaviour with Magnar doesn't fit. Quinn on the other hand is most definitely being a tsundere with her broccoli talk. She is just weirdly comfortable with sex for a tsundere.
Bella on the other hand in spite of a few tsundere moments is a kuudere. "Kuu" in this context is Engrish for "cool" and refers to their general behaviour of polite distance that is considered proper and professional. They are generally described as emotionless. A kuudere is surrounded by a wall of ice which melts when they fall in love. Bella does resist her emotions initially as a tsundere would, but it is not out of embarrassment. She resists because social conventions tell her that the relationship is wrong and giving in will have consequences and that is a kuudere thing to do. Another reason for Bella to resist would be fear of being hurt if the relationship fails. She never actually expresses that fear, but it would be very natural.
You are using the term in its old meaning that blankets some rather different personality types. It's basically the same as using the word gay to describe someone bright and happy. In that sense Derek is gay, but Troy and Chad aren't.
