Except that Jimi Hendrix definitely knew music theory, no idea why you'd think he didn't. He had a great understanding of what he was playing.
He had a music theory I'm sure, but the overlap of that with what's currently being taught in conservatories (let alone what was taught in his time), I'm less sure about.
