My knee-jerk reaction is that I don't think the action group should be styled as overdue because there is an action within it that is overdue. I don't think it has anything to do with my bit about reasoning due dates, though. You don't style a project as overdue when it contains an overdue action, but on the other hand, you do have the badges to indicate that. Hmm...have to agree that if you're in the habit of making large projects and keeping them collapsed, finding out which group to open isn't very convenient at present!

Here's a wild idea: option-clicking on the badge of a project with one or more overdue actions selects the project and opens whatever groups necessary to reveal all overdue actions and any prerequisite actions.
