TCP::collect would help https://devcentral.f5.com/wiki/iRules.TCP__collect.ashx

Just you need to find out how much length of TCP you need to collect to find google.com. I would not collect all TCP data.

when CLIENT_ACCEPTED {
  TCP::collect 15
}
when CLIENT_DATA {
  if { [TCP::payload] contains "XYZ" } {
     pool xyz_servers
  } else {
     pool web_servers
 }
 TCP::release
}
