Has anyone actually confirmed that Chrome is continuously sending audio back to Google? I highly doubt that this is the case. Instead, the plug in knows how to recognize "OK Google" all by itself. Once activated, then it starts sending audio data.
IF it where really listening even when inactive, then people would be complaining about it sucking up bandwidth and data allotments.
