I got confused after reading about spherical electron, would there really be some type of unknown particles popping in and out of existence within the virtual particle cloud around the electron that give electron it's property? Why is it important for the electron to have electric dipole moment?

If you have two classical static electric charges and wish to compute potentials and electric field, you can approximate with multipole expansion.

Because, you can have separately charged particles. Contrast to magnetism, there is no such thing as magnetic monopole.
