In v3.0 no typeconverters are longer needed for Enums. Now you can use TypeImports. For more information download the beta and read the "Enums for type shortcuts and TypeImports files" section in the manual.
This resolves the type mapping problem on LLBLGen project. Now, you have to write your enum types; if you want to automate this, you can write a task performer (like the one discussed above) to pull data from db and write a code file with enums.
