Yea, but troll farms influence US elections, and US elections play a role in the war in Ukraine.

An example of this would be Trump deciding to buy diesel from Russia, which helps Russia fund their war against Ukraine.

So stopping troll farms can help work towards the goal of getting Russia to leave their country.

I thought their goal was to get Russia to leave their country.

Well... it's to debilitate the Russian economy until Russians can no longer force-project across the border.

But anyone who believes Yandex was the soft underbelly of Moscow is going to be disappointed. Russian troops aren't going to leave because a data center got lit up. On the contrary, this becomes further agitation within Russia to spend an increasing amount of domestic wealth and civilian lives flinging firebombs at Ukrainian infrastructure. With the intended goal of debilitating the Ukrainian economy until Ukrainians can no longer force-project over the border.

This is purely a war of attrition. There's no target either side could hit that would end it, prior to a national political realignment or a wholesale economic collapse. Even if one side managed to dome off Putin or Zelensky, the war would drag on under their immediate successors.
