I think you misread the origin of the Judaeo-Spanish ladino. From the wikipedia page [1] :

"This Judaeo-Spanish ladino should not be confused with the ladino or Ladin language spoken in part of North-Eastern Italy, which is closely related with the rumantsch-ladin of Swiss Grisons (it is disputed whether or not they form a common Rhaeto-Romance language) and has nothing to do with either Jews or Spanish beyond being, like Spanish, a Romance language, a property they share with French, Italian, Portuguese and Romanian."
