As of November 2018, Jenny Slate was in talks to star in the lead role, returning from previous appearances. In an interview with The Hollywood Reporter she mentioned that it was time for the character to get his own movie, calling him "quite a charismatic character in movies that has yet to be fully exploited beyond small cameos."

He described Girls Rules as an emotional and friendship showcase, driving themes such as effective responsibility and familiarity, exploring elements of betrayal, paranoia and mystery, things the comic series did "which was great with the twists and turns it took". The creatives also drew inspiration from "friend travel" novels, along with contemporary television series like Sherlock (2010-2017). Mckay said that the series would serve as a continuation of the Lego Batman story and would follow directly from the in-development film Lego Dimensions (2023), which he found to be a "fun idea". He also said that the series would uncover some of the things that have not been shown in other appearances of the character Harley Quinn, such as Margot Robbie's version. Zoë Kravitz described the series as "a very grounded earthy drama" that "dealt with real human issues unnoticed and dealt with trust".
