I agree it's not productive to try to create things for specific learning styles especially as the theory is not proven.
People learn when the content is relevant to them, when it builds upon their existing knowledge, and when they are challenged to apply what they have learned.
It can be helpful in a long course to to mix things up so that different sections have a different "learning style" (i.e. just a variety of different types of activity) because doing sections in a different way makes the content more distinct to the learner and helps them remember and differentiate the sections more easily when they think about what they learned after the course. However, the way you present the content should always be driven by the content itself and what the learner needs to do with it after the course rather than insisting that content has to be presented in a particular way to meet a learning style.
