Linking Teams to a Communication site?

Toby McDaid Are there specific features of a Communications site that you want to use, ones that a Team Site doesn't provide? Or are you just interested in a Communications site because it allows everyone permission to it by default?

If you are only concerned about access and not features, have you thought about granting permissions to the connected Team site by using "old fashioned" SharePoint permissions?

What I mean by this is that instead of adding the non-IT users to the Members group of the IT Team, you would go to the SharePoint site and add them to the SharePoint Visitors group which is found in the Site Permissions -> Advanced Permissions Settings page. This way, your IT Team members will be able use Teams and everything else as members of that group, while other people can be granted access to just the SharePoint team site.
