Master Sol will most certainly inform Master Vernestra Rwoh or the Jedi Council about the Sith's survival. In Star Wars: Episode I - The Phantom Menace, Qui-Gon Jinn discovered Darth Maul and informed the Council right away. But since they have to report to the Republic Senate and then deal with politics, Master Vernestra does not want to report to the High Council.
It's unlikely that Master Vernestra could conceal this information from other Jedi for very long, even though she might be able to keep things quiet for a while. Sol and Mae may or may not return to Coruscant, but in either case, Master Vernestra will have to justify the deaths of so many Jedi. With almost ten people dead, it's harder to keep this information secret today. Because of the Jedi massacre and Qimir and the Sith's ability to stay concealed, Mae and Sol's survival raises a lot of issues.
It was formerly thought that none of the Acolyte's characters would survive to recount the story of the Sith. Although it appears that this is still Qimir's objective, it might not be achievable. If the Jedi discover that the Sith are still alive, then those issues will need to be covered in The Acolyte's final three episodes. The Acolyte must explain to the Jedi Council why they were unaware of this episode during The Phantom Menace, if they come to know. To stay within Star Wars Canon, the program needs to make sense of The Acolyte's plot and the events of The Phantom Menace.
