That doesn’t mean that it couldn’t be a medieval copy of a roman copy of an etruscan original.
A lot of our ancient greek statues turned out to be roman copies of greek originals.
That’s very true. By Roman times, the Greeks had been making bronze statues for foreign markets, including the Etruscans, for a while, but they weren’t the only ones making bronzes. If memory serves, there’s at least one surviving Roman marble copy of a Greek bronze original, and one of the Pompeiian frescoes depicts a mythological scene, and one of the characters appears to be a painting made from a bronze statue for its original. :’)
