Totally untested but something like..

iptables -t nat -I OUTPUT  --dest ! [GOOGLE ADDRESS] -p tcp --dport 80 -j DNAT --to-dest [IP ADDRESS TO SEND TO]

Notes: 

1) Note the ! that is the traditional NOT that you have come to love in most programming languages
2) You can specity a range of addresses like 123.123.0.0/16, which is heavy binary crunching saying 123.123.*.*
3) Make sure iptables is enabled (sudo iptables -L)
4) Since you're hacking on the kernel firewall, sudo is required for everything
5) Getting the correct ip address(es) for google may prove to be tricky
6) Iptables adds won't survive a reboot without proper set, internet will tell you how to do that..
