I fail to see how a CP victory would somehow create a world without international laws. They would continue to exist and compliance with them be situational as it has always been. Developments like international conferences and organisations trying to secure diplomatic and economic connections would continue in some form or another. Not because of idealism but the simple interest of preventing another war like WW1. CP or Entente, a WW1 that goes beyond 1915 is one that no faction other than the US can win. The best they can hope for is a stunted victory. Measures would be taken to make another July Crisis unlikely. How those develope and if and when an UN analogue develops is open.
Also trying to present the OTL post-WW1 age as a period governed by international law rather than national and business interests is simply wrong. Germany and the Ottoman Empire getting crushed did not prevent any of the atrocities committed by both former CP members or Entente members. Wilsonian foreign policy was all about intervention in countries that did not play ball with US interests, neither Britain nor France had any compulsion about invading countries and crushing people trying to resist them. The Russian Empire was the most autocratic regime in the entire world and would have been rewarded for its own atrocius behaiviour against its disidents and minorites with even more land and influence if not for the collapse. The examples could go on but I'll leave it at that. Denying German and Ottoman war atrocities is wrong. But the sad reality is that none of the powers really had problems with actions like these unless they could be used to shore up the homefront against the other side.
