Well... in KR, Savinkov's ideology of National Renewal is derived from the ideology of Savinkov himself (who has a Jewish wife and worked occasionally with Jewish people, including the period of the Civil War) and his circle, as well as actual Russian right-wing intellectuals, who weren't the most wholesome people on the planet, but they didn't tend to express rigid anti-Semitic views. The National Renewal ideology with its focus on populism and appeal to peasantry has little connection to the reactionary organisations like Black Hundreds. There is a little reason for the upper circles of the NRPR to be anti-Semites.
Surely, there would be a widespread xenophobia, since Savinkov's Russia is still ultranationalist, but it would be caused by the rejection of Jews and other "non-Russian" nations to be Russified rather than by simply existing, like in Nazi Germany.
I tend to agree with KR devs on that, since the Civil War in KR was mostly restricted to Central Russia with little Jewish population, the White Army didn't tainted its reputation with the horrifying pogroms in the South of Russia. The fact that the Civil War occured mostly in the regions with the dominant Russian population would make it more look like the war of Russians against Russians, who were mislead by Communists, rather than the International Jewish plot.
