If we put shelter in place requirements on the society at large, how many people die because they can't get the services they need? What happens in elder care facilities? Dialysis facilities? Etc. . . .Eventually food and water and possibly power will become scarce, right? As much, if not all, of that is managed at the local level, what happens and who is responsible to figure it out?

I expect those who have been tasked to plan for these have come up with what needs to still function in a pandemic.  Just some thoughts:

Health services, but only the emergency & essential ones (for some definition of essential).  Optional procedures would be postponed.

Food supply services.  This situation will last for months.  You obviously can't shut down grocery stores, nor the distribution system that gets the groceries there, nor the food production system (for instance, General. Mills).  Note that some of our food is imported, so that shipping may need to continue.

Infrastructure:  Telecommunication, Power, water, sewage & trash.   Electricians & plumbers may be needed for emergency repairs.

Housing, to some extent.  Room & board still needs to provide meals. Apartments need to run, but maybe not motels.  Care facilities still need to provide care. (elder, orphan, disabled, rehab, homeless, ...)

Law Enforcement (and/or military law).  Jails & prisons.
Military.

Governing bodies should probably continue, but things like permits & licenses & courts may be suspended.   What about tax prep & collection?

Essential financial services (to move money around).

Transportation support: gasoline, etc. for the above services, but most gas stations would shut down.

Emergency construction repairs & supplies would need to function - Consider the tornado in Tennessee

Weather prediction.
