The Dark Knight Trilogy level is a category under the Individual Levels leaderboard here
What About Glitchless? (where you have to play through the full story normally without the glitches to skip to level 15)
This is something that gets brought up every once in a while. There is very little interest in glitchless categories in the LEGO community as a category like this would simply be boring in most games. A lot of this game's skips are pretty simple and save a lot of time. Simply put people do not want to speedrun without the cool stuff, a category where you do not do level skips exists (No Levels Early), but it still uses plenty of glitches to save time, and it's what makes the run cool.
There is also a problem in defining what a glitch is, and there is usually a problem fully defining a ruleset for such a category. But again the main thing is that nobody really wants to run something like this. You are obviously welcome to do a run by your own rules, but a seperate category will not be made. If you want to speedrun this or any LEGO game and you need help with something, make sure to join the LEGO Speedrunning Discord and ask any questions you might have!
