Creating a device group structure
There is an official LogicMonitor python SDK at https://www.logicmonitor.com/support/rest-api-developers-guide/logicmonitor-sdks and its documentation is at https://www.logicmonitor.com/support-files/rest-api-developers-guide/sdks/docs/#api-LM-addDeviceGroup. I don't really use python myself and I've never used it so I can't really provide more details there myself. I would start there.
If you want to look at the more generic API calls, they are documented at https://www.logicmonitor.com/swagger-ui-master/dist/ and the one to create folders (LM calls them Groups) is /device/groups/ for resources and /website/groups/ for websites. I find the Swagger documentation good for knowing what is available but very lacking in parameters and examples but they are better documented with the older v1 documentation (Swagger is v2) at https://www.logicmonitor.com/support/rest-api-developers-guide/v1/devices/about-the-device-resource (see tree on the left).
