I'm trying to understand how my load balance software does not become a single-point-of-failure. Do load-balancing software usually support failover/ha for themselves?

Ideally, you would use a pair of clustered load balancers in a active/passive failover configuration.
Yes, Traffic is configured to hit a Floating Virtual IP, when the master load balancer fails the slave detects this, brings up the Floating IP and sends a load of gratuitous ARPs to the network. You can achieve this with VRRP, Keepalived, CARP etc. The Loadbalancer.org appliances use HA-Linux & HAProxy.
