“Tasting like alcohol” is a bit beside the point, IMO. What limits mocktails is that many ingredients and flavors dissolve in alcohol that don’t dissolve well in water.
Yeah, though you can largely get around this if you don't have a reason to strictly avoid alcohol per se. A bit of bitters in a mocktail is not going to give you any of the physiological effects of alcohol consumption. If you're in AA or a practicing muslim or have some other thing going on you know your business about it and probably (?) wouldn't do this. But for most people it's fine.
