As you've probably gathered by now you can't reset your TERM variable
in the current process.

However, in vi there IS a way to change your terminal type.
The way to do it is to go into ex, change it and go back into vi.
The commands are :

Q			(put's you in ex)
set term=term_name
vi			(put's you in vi)
