Not quite. Google still has access to those IPs when it receives the request from the browser and could be compelled to store them by US intelligence. Thus data are being transferred to a party that can not adequately protect them. So in this case, as I understand it, the solution would have to be something more elaborate, like proxying the analytics requests through the server to strip the original IP address. Which I presume Google isn't very eager to allow.
Lots of other tech companies, as I understand it, choose not to be "compelled" to store something they don't want to store. Apple being the prime example.
