It's a main stream franchise, it's all over the place.
Found plenty releases on private German trackers (e.g. Robert.Jordan.-.Das.Rad.der.Zeit.-.01.-.37.Komplett.128kbit.MP3 about 32 GiB) or Usenet (House-of-Usenet board also 1 to 37 or German indexer scenenzbs.com Robert Jordan - Das Rad der Zeit - Band 01 - Drohende Schatten) or file hoster boards (like boerse DOT cx).
edit: Also available on MAM (in M4A file format).
Using file hosters instead of Usenet, that's a Paddlin'. Using JD2 instead of PyLoad, that's a Paddlin'. Using a headless version of JD2, that's a Paddlin'. Using an overpriced RPI, that's a Paddlin'.
The first question would be if you have any experience in torrenting in general and private trackers in particular?
Some trackers are notorious hard to join or even completely closed, however others have open signups or application signups. You are also missing some German private trackers in your list.
Some German private trackers like the already mentioned World-of-Tomorrow or SpeedTorrent Reloaded or The Shinning allow application signup, if you are already experienced in trackers. For other trackers like Immortuous one can signup on their forums and apply for an invitation. Just visit their sites and look for an application/signup link.
Your question is too generic to provide more helpful answers.
Ditch OCH and switch to Usenet. I still regret not switching earlier. File hosters are outdated (from the usability perspective), restricted (in terms of usage), and overpriced.
There is no automation for file hosters. Solving filecrypt captchas and pushing to jdownloader is not possible to automate.
PS: It's called file hoster not OCH.
