I am looking for a circuit whose transfer function (V(z)/I(z)) comprises
just two poles. Is it possible to build such a circuit using just RLC
elements?

Thanks for your help

Theoretically, how about this:

o----------o-----o

Practically, any real circuit will have an infinite number of poles and
zeros; at lower frequencies you can very effectively pretend that the
circuit matches theory exactly.
