This is false. I already quoted some of the indictments that specifically indicate that the Russian campaign was primarily directed at helping Trump and hurting Clinton.
Again, page 17 of the indictment:
43. By 2016, Defendants and their co-conspirators used their fictitious online personas to interfere with the 2016 U.S. presidential election. They engaged in operations primarily intended to communicate derogatory information about Hillary Clinton, to denigrate other candidates such as Ted Cruz and Marco Rubio, and to support Bernie Sanders and then-candidate Donald Trump.
a. On or about February 10, 2016, Defendants and their co-conspirators internally circulated an outline of themes for future content to be posted to ORGANIZATION-controlled social media accounts. Specialists were instructed to post content that focused on “politics in the USA” and to “use any opportunity to criticize Hillary and the rest (except Sanders and Trump—we support them).”
b. On or about September 14, 2016, in an internal review of an ORGANIZATION- created and controlled Facebook group called “Secured Borders,” the account specialist was criticized for having a “low number of posts dedicated to criticizing Hillary Clinton” and was told “it is imperative to intensify criticizing Hillary Clinton” in future posts.
