Las Vegas Metropolitan Police are on a 700 MHz P25 Phase II system which should already be in your Home Patrol 2 database if you use Sentinel (as I understand it) - if you're already picking them up you're good to go with that agency.
Everything that was on the analog S.N.A.C.C. 800 MHz system, over a dozen agencies, are now using the digital S.N.A.C.C. P25 Phase I system and that includes all the local fire departments for Clark County, Las Vegas, Boulder City, and Henderson. I'm not 100% certain that the Sentinel database has all that necessary info but I'm going to guess it does (I don't own a physical scanner but I'm aware of Sentinel and how it works with Uniden scanners). The relevant database page for info is here:
That's what the Sentinel database might show because it's still got TGID info from the old analog system - 41008 is indeed the old analog system TGID for Clark County Fire Department - West Dispatch - Battalion 2.
Having said that - and the entire system is still technically a Motorola 800 MHz system, just using digital hardware now - the new digital system TGID for that same channel is 2563.
All that matters is if you're hearing actual broadcasts - you can fix up the Sentinel database info later on or perhaps an update will be issued that brings it up to speed with respect to the now different 4-digit decimal TGID numbers instead of the old 5-digit ones.
