Ive personally never seen a liberty with-out A/C but there may be some out there. I know on some vehicles without A/C they just mount a pulley in place of the A/C compressor so even if it didnt come with the A/C you couldnt do that.
If the clutch is bad then just dont use the A/C. Unplug the wire going to the compressor to make sure it doesnt kick on at all. Remember, it kicks on when you have the defrost on as well.
If the bearings are going out of the compressor then you may not have a choice but to replace it.
We had a compressor with bad bearings going out of a 94 grand Cherokee and we ran it for almost a year like that. The belt squealed like no other at times(mostly when hot) but it lasted. I do not recommend this but sometimes you cannot help it. If you do try to ride it out, it may not be a bad idea to go ahead and pick up a belt incase the current one eventually breaks from the added stress of the bad bearings. That way you could at least put the new belt on and get it somewhere to get worked on and not be stranded.
Where are you located? Maybe a lost member with some know-how lives in your current location and could help out.
If you need to get the belt off to try and fix it yourself, its very quick and easy to do. Here is a write-up with some pics on how to do it:
