No Roku player has Bluetooth capabilities. The very old Roku 2 XS had a Bluetooth remote, but it wasn't capable of connecting to remote speakers. You cannot connect your Roku Stick to anything wirelessly, other then the remote it came with and your WiFi network.
Roku TVs have the ability to wirelessly connect to a Roku Soundbar and remote speakers, but that is exclusive to the TV models, and doesn't work with players. I don't know if the Roku Soundbar uses BT to connect to the TV, or if it's using WiFi Direct as the remotes do.
Dan Roku Stick (3600), Ultra (4640), Ultra (4670), Ultra (4800), Premiere (3920), Insignia 720p Roku TV, Sharp 4K Roku TV, Nvidia Shield, Windows 10 Pro x64 running Serviio and Plex on a wired Gigabit network.
The roku Soundbar connects to the tv by hdmi, since it has roku streamer built-in and has to send audio & video to the tv. And it responds to both IR & wifi remote signals. But Roku Soundbar has Bluetooth, but its a receiver not a transmitter it won't send sound to BT speakers. It can receive BT signals from a cellphone or tablet so you listen to music through the soundbar.
Your streaming stick sends its picture and sound to the tv via the HDMI connection. You need to find a way to connect your JBL to the tv.
Or are you just trying to occasionally use the JBL for private listening just of the stuff on the Roku? The Roku app for mobile devices has a provision for remote listening. If you install it on a bluetooth equipped phone or tablet that is connected to the same net as your Roku you should be able to pair your JBL to the remote device and use the remote listening capability of the Roku app through your speaker.
