Schools want to use Google Search, but without "AI Overview" or other LLM interfaces in students' search experience.
Providing a hobbled version of Search that isn't what students use at home isn't exactly teaching useful skills, is it?
That makes about as much sense asking students to use MS-WORD for DOS instead of Google Docs. What's the point?
If you want your students to be able to use Google Search, then you should be giving them the real Google Search the rest of the world uses.
