Here's why I suggested a lawyer: you keep insisting that EU country has jurisdiction over, say, US company.
That is false and a lawyer would explain the notion of jurisdiction to you. Doing research apparently is not enough.
Unless I'm totally mis-reading this and the hypothetical company you're describing has presence in China/Russia/EU/wherever, in which I go back to "moot point" (because at that point you should consult professionals and not strangers on the internet).
The idea that a Germany has jurisdiction to enforce German business-related laws over company based in US (or Canada, or Peru or Belgium) is ludicrous.
Even if I sell to Germans, Germany can't make me put an Impressum information on my website, make me stop selling "Mein Kampf", make me collect VAT, make me pay German business taxes (all things that German companies must do).
Or make me comply with their data retention laws.
If they tried any of that, US government would put them firmly in place (and vice versa, if US tried to make German businesses comply with, say, DMCA, Germany would put them in place).
I repeat: Germany has no jurisdiction over US business but a clear insanity of such scheme doesn't seem to stop you from militantly spreading this completely false idea of how law works across borders.
But hey, I'm easily convinced with facts.
Show me a single case of a fully US based company that was successfully prosecuted by government of a country that is not US for not complying with non-US laws.
