Is there any conceptual difference between topological insulator (TI), and topological band insulator (TBI)? And if there is, what would it be?

Topological insulators are materials which are insulating in the bulk, but have conducting states on their surface. These can be realized even in strongly correlated systems where the band theory of solids does not hold.

Topological band insulators form a subset of topological insulators which can be described using band theory.

    $\begingroup$ If you want to dig deeper into topological insulators, to start with I would suggest Bernevig's book. This is essentially band theory. Interacting topological insulators are relatively new and currently a subject of intense research. Here is a review article. Disclaimer: I know nothing about your background, so pardon me if this isn't helpful. $\endgroup$ – heisenberg Dec 10 '20 at 21:06
