You'll have to push the "use $ or not" decision to the Sage level. Try
something like this:
\begin{sagesilent}
def f(x, y):
if y == 0:
return 'undefined'
else:
return '${0}$'.format(latex(x/y))
\end{sagesilent}
abc \sagestr{f(1, 2)} def \sagestr{f(1, 0)} ghi
That may be a little unsatisfying, but it should work. You could also
make your typing a little easier with something like
\newcommand{\foo}[2]{\sagestr{f(#1,#2)}}
(With "foo" and "f" changed to something meaningful.) Then you do
\foo{1}{2} in your document and it's easier to understand.
