how to disable admin of all multisite

You have to have AN admin. Now it can be your Super Admin account, but there must be an admin.

I’m assuming you want people to be able to auto-create blogs but only have the ability to write posts, is that correct?

yes you are correct,
i want my user to have a blog like blogger.com but in their blog they can create page and post and select theme and nothing else.
Everything else will be done by super admin like plugin available to them, etc
