Correct in regard to Hubitat compatiblity with Lutron. On Hubitat, the Lutron Smart Bridge Pro is required for you to gain access to the telnet capability, since that's how the Hubitat Lutron Integrator application works. Hubitat also supports RA2 Select Main Repeaters (RR-SEL-REP2-BL), so if you are only interested in Pico remotes, and you can get one of those for a good price, then it might be worth it to you. However, while they do support Pico remotes, they not support the less expensive Caséta dimmers and switches. You would have to use the pricier Radio RA2 devices if you ever wanted to add anything but Pico remotes down the line.
Home Assistant on the other hand, approaches it differently and they are able to use theses bridges:
- Lutron Caséta Smart Hub (L-BDG2-WH)
- Lutron Caséta Smart Bridge PRO (L-BDGPRO2-WH)
- RA2 Select Main Repeaters (RR-SEL-REP2-BL)
- QSX Processor (HQP7)
- RadioRA 3 All-in-One Processor (RR-PROC3)
If you're not already running Home Assistant and you have no intention of adding it, then it's a moot point. Get the Hubitat compatible bridge, or do not. There is no try. 
However, if you do run HA or have a desire to add it for compatibility with even more smart home devices you can spend your money on 
, then you could run the HA Lutron integration with a regular Smart Bridge, and also run the HA Hue integration instead of Hubitat's. That would allow you control the lights from Pico remotes via HA, and any light that you want to control by automation from Hubitat, you could do so by bringing the Hue lights from HA to HE via Home Assistant Device Bridge. If you needed or wanted to control anything else or a non Hue light, there are a couple of ways to do that which all work very well (i.e. Virtual switches, HE > HA integration, etc.).
