Why is the shell not part of the operating system itself?

Operating systems do 2 things: (1). Providing an easier abstraction layer (system calls) for user programs to access the real HW machine. (2). It manages the system resource. It this view, the shell is not considered as part of the operating system because: (1). It acts as a interpreter(from user command to system calls) only, and (2). It runs in user mode, and (3). It is highly possible to replace the shell if you don't like one.

What is the difference between system call and library function call?

On one level, there is no difference. They are both function calls. The only difference is in what they do. System calls do something the user program cannot do; something having to do with system resources: memory, files, devices, network, terminals, processes etc. However, system calls are usually implemented by library function calls because, at the root of the matter, a C or C++ program can only invoke function calls to call upon the operating system to do things.
