I could not find a counterexample to the claim that the transfer function of an RLC system can only have zeros at the origin. Is this a true statement?
Electronic – Is it possible for the transfer function of an RLC system to have zeros other than at the origin

One pole, one zero. Neither one is at the origin.
Or, even simpler, if you're willing to consider a transimpedance transfer function:

The transimpedance (\$v_{out}/i_{in}\$) has just one zero, and it's not at the origin.
