That's a very narrow (and in my opinion even wrong) understanding of what constitutes a democracy. Prosecuting companies via criminal lawsuits might be the American way but that does not mean every democracy has to have those same rules. If an administration fines a company and there is the possibility to appeal to a court that is also a democratic process. My homecountry Germany uses this process (companies are never sued in a criminal lawsuit) and I don't see a reason why that would be undemocratic.
