Biden's family relation to Ukraine is mostly irrelevant in the grand scheme. Even someone like Nuland who was literaly directly involved in the maidan coup is far more of a direct cause for the war than Hunter.

For staters, Operation Aerodynamic

The purpose of Project AERODYNAMIC is to provide for the exploitation and expansion of the Anti-Soviet Ukrainian resistance movement for cold war and hot war purposes. Such groups as the Ukrainian Supreme Council of Liberation (UHVR), its military adjunct, the Ukrainian Insurgent Army (UPA), the Organization of Ukrainian Nationalists (OUN all in the Ukraine, the Foreign Representation of the Supreme Council of Liberation (ZPUHVR) in Western Europe and the United States, and other Ukrainian organizations such as the Foreign Sections of the Organization of Ukrainian Nationalists (ZchOUN), etc., will be utilized.[5]

OUN is literaly the Ukrainian WW2 nazis still alive today.
