No more than the rules most religious orders have regarding one who becomes a part of that order like a priest, a monk or a nun. And since the Jedi Order is a bit of a religious order, it is to be expected. We don't know much of anything about the nineteen who left before Dooku, except for Darth Ruin. We don't know if they married or not, if they had children or not or outside of the two mentioned, went rogue or not. They might've all continued to live a life without any of those weaknesses occurring. But the Jedi Council did give trust to members of the Order, while they were a part of it. And they would continue afterwards, such as we saw with Dooku when he left. They trusted them to adhere to the principles of the Jedi Code both within and outside of the Temple walls. According to "Jedi Apprentice", a Padawan who has not been accepted by a Knight or an experienced Master by age thirteen, will serve the Republic as part of the AgriCorps. Essentially becoming farmers. Obi-wan almost joined them because he still had some anger issues which wasn't dangerous, but was not what Qui-gon was looking for after his last Apprentice. It was through the intervention of Yoda, that they were paired up on the same transport which then led them to become an official Master/Padawan team. The Jedi would keep an eye on them to determine if they were continuing to behave. They were predominately a huge army of Sith Lords, thousands upon thousands. There were probably some droids and allies like the Mandalorians, but it was mostly the Sith. The Jedi allied themselves with Republic commandos and military officers and when necessary, local resistance cells.
