JLU Could use Batman but not his rogue gallery once The Batman started and The Batman couldn't use Ra's, Two-Face (Hence Clayface I basically being their Two-Face), or Scarecrow due to the Nolan films for some weird reason. Also JLU couldn't use Aquaman as a series regular due to CW developing a Aquaman show. Last JLU couldn't use Blue Beetle or Plastic-Man due to rights issue which has since been ended.
My point is some of these were rights issues others were just weird no's so WB has a weird history especially with Bats of what can been shown were and it seems outside of cameos like the finale in Gotham, the flashback of the pilot of the BOP tv series, and Nightwing's vision of Crazy Batman on Titans the character is only used on the big screen for live action.
