Yes, this article doesn't appear to have any independent sourcing, it just cites the Jacobin one that you link: "de acordo com a revista norte-americana Jacobin" ("according to the North American magazine Jacobin").
The New Statesman also published an obituary that they had to retract.
I found the title of this article amusing although the publication isn't one that I often read: "'Manufacturing Obituaries': Media Falsely Reports Noam Chomsky's Death" https://www.commondreams.org/news/noam-chomsky-not-dead
