What are you talking about? Every "green" party I know in Europe is very much against the war in Ukraine and holds Russia responsible. They are about as anti Russia as it gets. Green parties are also very much pro Europe, they want a stronger Europe with more members and cooperation in the EU.
Green parties are either center-left or totally left leaning. Green parties usually get a big chunk of votes, not only marginal like in the US.
Russia is heavily funding and supporting the right and far right parties, who are almost all against a unified Europe. Russia is doing their best to break up the EU with campaigns of misinformation, bots, advertising and direct/indirect funding of right wing political parties.
And Russia is succeeding as well with the far right on the rise all over Europe. They already got Brexit through against all odds and are now working on breaking up the rest. In Germany the rise of the right is still fresh, so there is a lot of resistance. But other countries are much less resistant.
