Lime mud and ooze form by precipitation (mostly induced by living things).
Your arguement doesn't avoid the problem. The microscopic texture of many
limestones reveals that they consist of myriad tiny fossils, and many
tropical warm-water algae produce lime mud (with no distinctive
fossilizable features) as their skeletons break down. Oxygen and carbon
isotopes of any carbonate may also reveal biological influence on their
formation, but I don't know how widely this has been tested.

Almost all limestone and much dolomite is fossiliferous; I think this is
considered an indication of post-creation formation by most YECs. In many
cases, there are traces of predation preserved on fossils in the limestone;
I think some YEC models claim that this does not appear until late.
