I’m saying they seized on it as something they could use to push division between people.

These studies are seeing patterns in noise. That's why the narrative changed over time - it used to be "Russian twitter bots got Trump elected!" and now it's "they're supporting both sides .... to sow division!".
The former claim was extremely implausible but at least it had some sort of inner logic to it, in that Trump was more friendly to Russia than Clinton. The new spin doesn't even make logical sense. However it makes perfect sense if you're just picking random Twitter users and trying to explain their behaviour through the prism of some convoluted conspiracy.
Sure it does. The appearance of a wide division in our political landscape leads to a wide division in our political landscape. People tend to "pick sides" in political fights and when something gives the appearance of a serious political dispute, people are motivated to pick sides and entrench their opinions. This is in keeping with getting Trump elected, as a large part of his support was due to the fear created by the appearance of growing civil unrest. None of this is particularly hard to understand.
There's a deeper issue here too. It paints the posting of political talking points from both sides of a US election as generic "sowing division". That is a world view that is quite totalitarian. I could describe it equally as "invigorating the democratic process by increasing interest in the election" and be no less accurate.

You haven't shown that, you haven't even laid the groundwork for that. It's actually the first time I've ever seen such a claim. Most analyses of why he won point to the weakness of Clinton, his policies in immigration and trade deals, his opposition to political correctness and so on. Not "the appearance of growing civil unrest".
