Yes you can. This is called a 2 + 1 set-up. 2 Galera nodes + 1 Galera arbitrator sitting on one of the app-server nodes. But it is NOT a recommended set-up.
An alternative would be to put the Load Balancer on the app-servers. Then you have 3 db nodes and 3 app servers. But from the maintenance point of view this is more work than 2 central load balancers.
