Your goal, if you choose to accept it, is to make sure Germany is never united. Good luck.
Britain or France could have at the very least made it significantly more difficult. If either the USA or the USSR had opposed unification after 1989, it would not have happened. Even against just Britain and France, Kohl could well have chosen his European project over unification (which, after all, he knew would be very difficult even under the most favourable circumstances). But I think your best bet is that, for whatever reason, the USA decides it will not support unification.
Have Austria and its german allies win the war in 1866. They actually were rather close to winning.
You could even have France enter the coalition against Prussia.
Or start earlier and have Napoleon being victories of the russian campaign or of the 6th coalition campaign (he actually was rather close to winning it). The french empire keeps dominating the core of Germany in the Rhineland confederacy, and keeps Austria and Prussia (or what remained of it) out of german affairs.
You can't stop a nation from becoming a nation.
