As the Treaty of Brest-Litovsk showed, the Germans were prepared to parlay with the Bolsheviks. Furthermore, there is evidence to suggest they actually funded Lenin's activities (there is a deficit in the accounts of his party which can only be explained by financial assistance from Germany).
If the Germans were prepared to support the Whites, then it might be a different matter, but that is not altogether clear.

Sure the Germans funded the Bolsheviks.
Brest-Litovsk was no "party". The Germans owned the Ukraine and felt no need to occupy Russia proper. Brest-Litovsk was a virtual capitulation by the Soviets to that fact.
