I just checked KLAS and KORH - all the approaches say "and hold" in the missed approach instructions. I'm not totally familiar with FAA procedures but it seems that it's normal to say "and hold" so I'd guess that the RNAV 19 is just a typo.
Anytime you're operating under IFR in controlled airspace you will require a clearance. Every clearance has a clearance limit. If you reach the clearance limit prior to receiving further clearance, you are to hold. I'm guessing that's why they don't specifically say "and hold" on Canadian plates - the clearance limit for an instrument approach being the MAHP.
