Thanks for confirming. It's generally a good idea to ensure variables are set in all cases. Or you can use info exists to check. But it's additional complexity with little benefit. 

when CLIENT_ACCEPTED {
   if { [IP::addr [IP::client_addr] equals 174.76.19.40] } {
      set log_ua 1
   }
}
when HTTP_REQUEST {
   if { [info exists log_ua] && $log_ua == 1 } {
      log local0. " 174.76.19.40 uses [HTTP::header value user_agent]"
   }
}
