Larry, MS Teams is based on O365 Groups. So, if there's a Group already in existence the folks who want to use Teams should be able to create the Team and attach it to the existing Group.
Additionally, there are some admin controls for groups, including ability to set naming convention and/or to specify which users can create groups.
