I'm not entirely sure without more context. 'Light novel' is a type of Japanese novel often aimed at a younger audience with some anime - like elements. 'Outaishihi' might be a name or a term specific to the story, and 'nante naritakunai' could roughly mean 'don't want to become such a thing'.
Many light novels explore themes of self - discovery and the struggle against pre - determined paths. If 'outaishihi ni nante naritakunai light novel' is about not wanting to become something related to 'outaishihi', it might be similar to other light novels where characters resist a certain fate or role. For instance, some light novels have characters who don't want to inherit a family business or a magical power because they fear the consequences or simply don't want the associated responsibilities. So, there could be similarities in the broader concept of resistance to a particular situation or identity.
