All subsections of the 2014 NEC 210.8(A & B) start off with "All 125v, single phase, 15- and 20-ampere receptacles…" I see no such requirement for 220v outlets. Can a 220v outlet be installed without GFCI protection? I'm thinking specifically in a workshop/garage setting, but this could apply to dryer or oven as well.

It is a 2020 NEC change
If your state is still on 2017 or earlier, you're fine. If you are on 2020 then this is the rule (unless you have a local exception).
This would apply to typical dryer receptacles. Ovens, however, are sometimes connected to a receptacle and sometimes hard-wired. If they use a receptacle then specific rules about location will determine whether they need GFCI or not.
