First. You have parasitic traffic from your LAN. Not from proxy.
Second. You can make HTTP-headers modifications on your proxy. In some
cases it can cause similar problems.

NP. I use transparent proxy in my infrastructure over 4 years, and seen
this problem just once. When one PC in LAN was infected with a virus.

Don't think so. Google uses not only one domain. What about youtube,
blogger.com, googleapis, gstatic etc.etc.? Also - what about it's HTTPS
versions?
The best way (and forget to traffic economy, os course) - identify all
google IP-ranges and bypass it by ACL on Cisco, for example. Completely.
But why would you do need cash?
