You would really like sqldelight[1] then. It takes the concept of an ORM and flips it on its head. Instead of mapping function calls to SQL statements, it lets you write SQL statements and then generates classes for you that have methods for those statements.
For instance, you could have a SQL statement like getCardsForFight: select * from fights where cardId = ? and titleFight = ?, and it would generate a class that has a method getCardsForFight(cardId: number, titleFight: number).
My understanding from reading the page was that flyweight translates trivial table access to SQL. For anything beyond that is seems to do exactly what you describe i.e. you write the query and it is creating a TypeScript API for the query. Which saves you the work of defining the interface and ensures some level of correctness of the mapping.
For instance, you could have a SQL statement like getCardsForFight: select * from fights where cardId = ? and titleFight = ?, and it would generate a class that has a method getCardsForFight(cardId: number, titleFight: number).
