TLS terminating is fine for most use cases (basic web services), but if you are protecting PII information you need to/should protect from external and internal threats. Maybe a disgruntled sys admin decides to capture data coming in from the load balancer between the service(s) and sell it to the highest bidder. If traffic is encrypted between the load balancer and underlying service, it makes it much harder to do.
