Mindscape LightSpeed has a free version for small databases and is similar to O / R Mapping capabilities. It includes a rich Visual Studio designer with all the schematics you could possibly want as a developer looking to avoid cumbersome mapping files.
If the database is bigger than the support of the free version then contact us as they are known to provide their software to students at no cost.

Presumably if you mention LLBLGen you are a .NET user - do you have access to Visual Studio? You can always use T4 - the code generator built into visual studio - I have used it with great success for generating code. All you need is some model that your code generation templates can read, and then you can use T4 to generate SQL or whatever you want.
