Absolutely Not. Kanaya has a gothic sophistication and maturity, along with her brooding goth aesthetic, that would make Anyone want to hug her.

While my obvious choice to hug is Karkat, that boy would probably hiss and thrash in my arms until I let him go. I can see Kanaya first be tense/surprised by physical contact if you hug her, but then she gives some pretty decent hugs when she gets comfortable.
