Disagree. There's no such thing as perfect certainty, but the only real question about Russian troll sponsorship is one of scale.

> US's sponsorship is objectively less probable: English being lingua franca hampers American wannabe "hybrid trolls"
This is an interesting observation, but I think you either underestimate American resources, or overestimate the logistics of online influence manipulation campaigns.
For illustration : there are about 1m fluent Russian speakers in the US, and about 4m fluent English speakers in Russia. Sure, it's a bigger talent pool : but both countries could rope in bilingual cyber propagandists by the thousands if they felt so inclined.
What?
gamergate, /pol, /b, alt-right, the_donald, antifa use online trolling. In context, saying a state actor uses online trolling is an extremely conservative claim. I'm sure there's online trolling in favor of and sponsored by US, Chinese and Macedonian interests (to name a few) too - but Russia's actions are much better documented.
