Can we maybe not waste our time with such stuff? I am also not quoting homeless guys from London here without providing any useful reference.
While OP's question with the notorious "EU country" is too vague to give any useful answer, US banks to collect details of signers of corporate bank accounts. And from there on, OP is old enough to read the FACTA agreement between the US and the jurisdiction he claimed to be resident of. He can then discover himself to what extent the US also reports data back. In most cases, they will. But not in all as some are only about to start reciprocal reporting (and that is also the reason of the differing views from your AI).
