Regarding the doll with hair that grows, even without a precise translation, it was possible to understand it's not a compliment...

First Kurumi thinks that to herself while she moves out of the scene, you could think of a contrast between what she thinks, and what Sawako thinks. Remember that from the begining of the show, Sawako almost always thinks the opposite of what reality is like regarding her relationships.

Then Yano and Chizu immediately thought what girls would usually think regarding Sawako.

And I think the very long hair doll has been shown at least 3 times.

Then there was a subtle pun in the Sawako changes her hair scene, with how her hair is in three simple parts with a funny animation.
I laughed hard at the begining of that "Hair sequence" I admit.

So yes, Kurumi wasn't thinking something really positive as a doll for Sawako.
