As PalJoey said, the OP is trying to create some bulls!t story about Olivo's choices that seeks to create a fantasy world in which Olivo turned down the role in some sort of alleged diva move and is now "kicking herself" for it, which more than silly, is a vicious and unnecessary way to twist the events.
It is very likely that Miranda was inspired by Olivo when he wrote the role of Angelica. It is very likely that she would be brilliant in the role. But the truth is that Olivo made a very public decision to step away from the pressures of Broadway--something tells me being a part of such a high-stakes show that became a wild phenomenon is exactly the sort of thing she would avoid. The truth is that Renee Elise Goldsberry auditioned for the role, and that Miranda has said that no one he saw for the part could handle the role like her. The truth is that Goldsberry is giving one of the great performances in musical theatre. The truth is that Lin-Manuel Miranda wrote one of the most brilliant female roles in the theatre, a role that actresses of color will continue to make their own and nail for as long as musical theatre exists.
