Hi @DLGross,
Do you want to get all of Teams Flows in every environment within Microsoft Flow?
I afraid that there is no way to achieve your needs in Microsoft Flow currently, you could only get all flows that you created in a specific environment within Microsoft Flow currently. If you would like this feature to be added in Microsoft Flow, please submit an idea to Flow Ideas Forum:
https://powerusers.microsoft.com/t5/Flow-Ideas/idb-p/FlowIdeas
If you would like to get all flows that you created in a specific environment, please add a "List My Flows" action of Flow management connector within your flow:
More details about Flow management connector, please check the following article:

The limit in using Flow management connector, please check the following article:
