No because google is not marketing their service for medical use. The doctor is responsible for the diagnosis/prescription, which they’re allowed to use any tool they deem necessary.

Medical devices are marketed for specific medical use, which doctors rely upon to do what’s medically expected. These devices will have an “expected use” and “indications for use” that largely cover how they are design/expected/tested for use. They need 510k clearance to be classified by the FDA as a medical device.
