It says that jacketed bullets need a crimp groove, but the Hornady 185 grain XTP don't have a groove.

With that said, many dies can be adjusted to seat and adequately grip the bullets. I loaded over 50,000 45ACP rounds before I got a taper crimp using standard RCBS dies.
The crimping grove in a bullet could be there for holding the core in place as much as a location for a seating depth, in most cases I ignore the grove all together, seeking accuracy and reliability.
What Bpost is saying is for a bullet to need a cannelure (or crimping groove as they call it) would mean a roll crimp not a taper crimp.
You do not need a crimping groove on the bullet for that die to work. It should just be taper crimped with or without a groove.

Got it. Thank you. So why does Lee say that it should have a groove on their website?
The only roll crimped rounds are for revolvers.
I'll defer to what dcs shooter said and that is the roll crimp is for revolvers. Some have adaptations so they can shoot a rimless round such as the .45 ACP, 9mm Luger, .380 Auto, or .40 S&W. A revolver can usually use a roll or tapered crimp. The semi-autos' I've loaded for can only take a taper crimp.
