Is it a true 1911? Lots of Llama and Star pistols have the 1911 look, but few parts are interchangeable.
If you want a bushing that is oversized on the outside and undersized on the inside, look for a G.I. match bushing. They can generally be found pretty cheap.
EGW does make excellent stuff, and if you provide the desired ID and OD, to the thousandth of an inch, they will make a custom bushing for you.
EDIT: Your Llama has a barrel that's smaller in OD than a standard 1911 barrel (~.578"-.580")? What size is it? I have the small-diameter bushing that came on my Colt .38 Super, and will send it to you if it's small enough that you could enlarge it to fit your barrel.
