re: I wonder how many teams are trying to copy LSU’s offense from 2019

None in the sense of running the same plays from the same exact formations. Ensminger is creative and always has been What they want to "COPY" is effectively a PRO QB situation where they have a graduate not being bothered by class room attendance or normal student activities for 2 full years coming to work with the coaches in the early AM and not leaving til late at night Notice UGA jumped into that game with a one year guy but LSU had Burrow to improve him 2 full seasons.

They also want a senior laden OL who have been in the weight room for years like LSU had. NFL style wr like LSU had and again the continuity of the OC. Those are the things all teams are trying to copy. Including LSU.
