I have already mentioned that there are several types of deposition in the limestone formation process, this includes both chemical precipitates and fossils.
Note the scale in the link below. (source: USGS)
Geology of National Parks
Limestone layers of that thickness take much more than the duration of Noah's flood.
You mentioned forams. I said rarely limestone with abundant forams will have hundreds of feet thickness. The foram-enriched layer may only be a few feet or at most a few tens of feet thick.
You also need to be aware that the water chemistry during the global flood should be very different from the normal seawater today. You can not use the current rate of carbonate pptn to model what could have happened in the global flood. I would say the Ca concentration in the ocean water should be sky high during the event. The temperature should also be higher. Not only the very fast precipitation of carbonate was possible, the deposition of carbonate layers should continue for a long time after the event of flood.
