I know about GnuCOBOL, but both projects have different goals and ideals.
Otterkit compiles to C#, and GnuCOBOL compiles to C. The two are meant for different use cases. You wouldn't use a huge C program in a .NET backend, it would be a pain to make it work correctly and difficult to maintain.
GnuCOBOL also doesn't support quite a bit of COBOL's features. It only supports the procedural part of the language, and that is only a small part of it compared to the object oriented side of COBOL. Otterkit will support both, and the new 2022 standard.
