Yeah, saving in LS wastes a lot of time because you have to go inside unlike Badlands, SF, Toreno's Ranch and LV where you can save outside and only lose out on a couple of seconds at most.
For a 100% run you are minimally forced inside 3 times, after Sweet & Kendl, picking up some spray paint some time between Tagging Up Turf and Nines and AKs and another spray paint pick-up some time after Burning Desire and before you leave Grove Street again. A 4 segmented LS would be tough, given that sometimes you aren't given the car/bike you want and of course any random crashes or incidents that may happen plus clock missions may not fully agree.
Taxi would essentially require a 5th part given how you need to completely avoid the airport and minimize traveling distances. If you don't care about the "in a row" bonuses you could split it up or even delay doing taxi all together though SF isn't exactly taxi friendly and by the time you do it in LV you've probably saved more time from using nitro taxis than the time you would save from not saving and money is pretty tight until you start exporting cars.
