Filoni isn't actually listed in the major credits of any of those three episodes (check the wiki page I tagged to your post), so his involvement was minimal. You actually have George Lucas to thank directly for most of those ideas. Besides, the Chosen One prophecy was more developed in the prequels than anywhere else in the saga.

Perhaps so, but Lucas didn’t enable TCW. The storytelling here is just superior. Just saying, there’s so much story to tell and I would have loved to see it in live action.

Also, supervising director: Dave Filoni.

^^ ???

Lucas absolutely enabled TCW 2008 to exist, he literally funded it out of his own pocket because he wanted it made that much

Filoni has stated before that when in doubt, he went straight to Lucas on ideas (this arc in particular)

@Shundy, just as @Jedi Sarith LeKit and @Red5T65 wrote.

The Clone Wars enabled by George Lucas to the point he was the one who hired Filoni for the position of supervising director. And he was indeed the supervising director, but he and Henry Gilroy basically did what Lucas told them to do. He often made this clear in several interviews:

"The story ideas are all generated by George Lucas directly. He comes in and says, we're going to o this story and we're going to do this story. " - Dave Filoni

"George gave Henry Gilroy and me a board idea of different groups or areas of the clone wars - the large-scale battles, the small-scale personal stories on the front lines, the senatorial intrigue, and the more roguish outer rim stories. The early plots were then hashed out by Henry and me. We would take those ideas back to George and he'd get us feedback and move things around, teach us if the idea worked within the Star Wars universe or not. Eventually the story ideas were driven more and more by George because he became so excited about the project. He started coming to us with a bunch of stories he wanted to tell, and we worked off his outlines after that." - Dave Filoni

"George is the Alpha and the Omega, and is involved in the story from beginning to end. On The Clone Wars, that means from the initial story idea until the final sound mix. I knew from the moment I got the job that The Clone Wars was going to be George's show. My job was to execute his vision and I have always tried my best to do that. " - Henry Gilroy

And it went the same way with this certain episode. In this video Dave Filoni shared details about the creation of it and it shows pretty well how big Lucas involvement was in the process:

Well, that’s nice to know. I still maintain that the execution of TCW is far better than the movies. I think the format lends itself to the scale of the story, which isn’t Lucas’ fault, but I feel the movies really blew past the real meat of the story and the TCW team salvaged that to a large degree. I read recently that Hayden Christiansen and Ewan McGregor both binged the series prior to the new Obi-Wan series and I’m hopeful that will result in a more believable link between the two of them in live action.
