There is not a complete and separate list of third party devices that are compatible with LabVIEW. However, NI has a library of instrument drivers where customers can find, download, or submit a driver to communicate with third-party instruments.
On the left-hand side you can narrow down the type of driver you are looking for. For example, when you click "Data Acquisition System" you will see the "Model" (shown in a red box) that can narrow down the devices that we know are compatible.
Note: This is not a comprehensive list, but it is a good place to start. Generally, if a device has a driver that works with LabVIEW then the device should be fine to use. Not all devices/drivers are tested by NI, so there is no guarantee that it will work perfectly.
