Place this as the first access_log line (order matters for these):

  access_Log none noTransactionError

I would also name that ACL something different. An IP address is not an
error and this choice of rule will prevent logging of *all* traffic from
that IP. "loadbalancer" would be clearer name.

I have not tested this, but you may want to add this extra condition so
when the LB sends actual HTTP it will appear in the logs:

  acl hasRequest has request
  acl dontLog all-of !hasRequest noTransactionError
  access_Log none dontLog
