if you select your clips in the bin, and right click and select source settings, you will find a colour management tab, where you can remove the luts.
At the bottom of the tab, you will see an “apply to all” button.
After that, you may need to find the “Update sequence” setting, if you have already cut with the shots with a lut attached, as the sequence will still show the lut, even after you have removed it from the source shots. From memory, i think you right click on the sequence, and you should find an “update sequence” tab. Next to that are options you can update, including Update all, or update colour transforms…or something like that.
