Usually when people talk about tuning kicks they're talking about kicks with a distinct tone like an 808 or a 909. Your regular old generic kick though you don't need to worry about "tuning" per say... just EQing nicely.
And yes you're right. Some EDM artist don't use huge kicks. It all depends what you are going for but I suppose if you don't want a huge kick than you shouldn't worry a ton about layering and such
