Can a physical load balancer offer failover as well? My worry is what if the load balancer itself fails? How to provide redundancy in such cases??

yes, most load balancers offer high availability in active/standby, some offer active/active, or active clusters. For physical devices in proximity, hardware failover is an option, but for virtual load balancers and physical load balancers too far apart will use network heartbeats.
