Hey @Zack_Barett!
You should be able to use the Google Maps JavaScript API in a custom component. Once you've set up the API in your console you can follow the steps here to get started.
Retool also supports using the Embed API in an iframe component.
I've added a JSON export of the former which you can import and play around with, let me know if that helps!
