It's healthy to depend on your coworkers for their specific knowledge. The landscape is too large for everyone to know everything, and honestly if I heard someone say this in an interview I would chalk it down to social deficits because this is not how life, businesses, etc. work

I think the key with this though is that it's good when everyone on a team has a working knowledge of something, and one person has expert knowledge. If one person knows everything there is to know, and everyone else knows nothing, you've created a massive dependency on the single person (which in the case of infrastructure code, could easily be a near existential problem for the company).

It’s unrealistic to expect the entire team to know how to build and safely operate IPv6 BGP anycast with an HTTP/2 tls load balancer, authentication and authorization, integrated with a modern observability platform and a zero downtime deployment CI process.

It is realistic to expect a small team to build the same in an industry standard way and hand of a clear, well documented API to the rest of the team.

Bespoke solutions need to deal with this complexity somehow, k8s provides a standard way to do so.

I'd consider knowing how to use the API to configure services and deploy new services to be a good definition of "working knowledge". You're right that everyone doesn't need to know the ins and outs of everything for sure, but if you observe at your company that everyone is relying on "the Kubernetes guy" to do everything related to Kubernetes, you've just re-invented an old-school ops team in an especially brittle way.
