Would an OS create kernel stack for user-level threads?

In a system where the kernel stack is separate from the process stack.

If the OS supports threads (as opposed to threads implemented in a library), yes it is likely to have a kernel stack for each thread.

In any protected system, the kernel stack is separate and protected from user mode access.
