How can I run a powershell script on an entire Azure management group to span multiple subscriptions? I need to export resource inventories from multiple subscriptions with a single run in the same file.

You will need to use Azure Resource Graph which supports PowerShell, CLI and Azure SDK for .NET.

Search-AzGraph -Query "Resources | summarize count()"
