Not aware of any series. Two possibilities occur to me "Power Records" released short book and story record sets about many DC heroes in the 1970s. However, no Justice League. There were adult audio dramas produced by Graphic Audio but alas, DC didn't renew the license and they aren't available anymore.
indirectly related to detectives: do you have any episodes of 'the justice league' radio program? cheers!
