I listen to a lot of radio in my shop and get interference from the LED's. Has anyone bought a filter that works for this type of thing?

very difficult to do so, you would be well served to contact the maker and get details of the model you have and what noise mitigation options you have.

You might be able to "home brew" a noise filter from capacitors to take the noise peaks to ground.
This was covered in a class I attended 60 years ago, it was built with disc ceramic capacitors back in the days of vacuum tubes.
As I recall, there were two capacitors configured in the shape of a Wye with the center point going to ground and the two arms connected to Line 1 and Line 2.

Might want to read this... good info on what's going on electrically with the power supply.

I had some, but I bought an adapter cable for the computer I have out in the garage and now I live stream the radio station in the Bose systems auxiliary port and it's perfect.

LED fixtures work totally different than incandescent or florescent. They use a "switching" DC power supply (like 99% of all electronic these days). These power supplies are tested for FCC compliance, but of course, nothing is perfect.
As stupid as it sounds, wrap the power supply loosely with aluminum foil might solve all of your problems (yes, RF does come out on the DC ouput line).

maybe ferrite beads?
