You can watch LindellTV on your Roku (and all other web content), by navigating to https://lindelltv.com/ on your phone or laptop and then casting it to your TV, or using an HDMI cable.
With my laptops, I generally use an HDMI cable for streaming directly to the TV. With my Android phones, I use some free apps from the Play Store that allow me to cast web content to the Roku. I generally use Web Video Caster, but other good ones are "Video and TV Cast for Roku" and Castify/Rokify.
