Toriyama's involvement in the Super anime is only just BARELY more than his involvement was in GT. Apart from the films, which he was certainly heavily involved in, and perhaps the manga, which is a very barebones retelling of his outline and occasionally features direct input and drawn pages from him, Toriyama otherwise isn't "writing" Super: he's providing very rough outlines and designs for other teams of writers to actually flesh out and do the heavy lifting bringing to life. This is similar to the first GT arc, where he got a "story consultant" credit, approved everything, drew the first round of character and technology designs, and created the premise (or at least, he named it "Grand Tour" and told Toei to go from there).
In terms of the creative process, GT and Super are hardly THAT far removed from one another, as they're both ultimately far more of Toei's original anime creations than they are Toriyama's. Super indeed has a bit more of Toriyama's hand in it than GT did thanks to those outlines and the core concepts coming straight from Toriyama past the first arc; but ultimately, its not by THAT much more when all's said and done.
With DB/Z, Toriyama was literally writing and drawing pretty much EVERYTHING himself week to week via the manga. The original series was for the most part very much an auteur's vision. Super by contrast is largely being crafted by a committee of Toei writers and artists, with Toriyama only responsible for the barest-most basic core ideas and story trajectory.
Even with regards to Toyotaro's manga: all Toriyama does with that is give the dude some bits of advise every now and again, and maybe occasionally help touch up or redraw a botched panel or two: and before you know it, everyone immediately blows this up into "Toriyama's practically drawing a new Dragon Ball manga!"
The whole thing reeks of desperation on the fans' end, and its honestly kind of sad at this point.
