When reading about the Paris Peace Conference (PPC) there is no mention of anything related to White Russia, apart from the USA being in favor of a strong united Russia to counter Japan, as far as I can find.
Why were the Russians, who were one of the first Entente to declare war and suffered majorly at the hand of the Germans not invited to the PPC?
Why should they? Russia already made peace and dropped out of World War 1 at that time. Also White Russia has no more claim to Russian government than the Bolsheviks. What use would it have been to invite them? There wasn't a legitimate government that could have spoken for the whole of Russia.
There were lots of Russians at the Paris Peace Conference, but they had no state behind them, so their opinions didn't carry a lot of weight. Stephen Bonsal's "Suitors and Suppliants" has a chapter on Russians at the peace conference, though some of it concerns reminiscences about pre-war experiences.
