The electron's spin dof can only become entangled with
the environment by an interaction with the environment.

explain spontaneous entanglement?
I've never heard the term and I don't know what it means.
You're way too modest. Take the case of a free Nitrogen molecule. It's
isolated, thus not entangled,

what I call "spontaneous entanglement".
Or better yet, consider electron with spin its only DoF. How does it
become entanglement if Joe the Plumber doesn't perform an SG experiment?
I dunno. It collides with a He atom. It passes near a magnet. It can
get entangled with something else lots of different ways.
Specifically, when spontaneous entanglement occurs, what role has spin
wf in this process?
The interaction Hamiltonian of the system wf (electron+stuff it's
interacting with) had a term involving the magnetic moment of the electron.
I'm trying to understand the general process whereby free systems
become entangled with their environments, which, IIUC, is a key
process in decoherence. AG
Entangled doesn't necessarily mean "entangled with the environment".
