What options are available to me if I don't want to go down the route of replacing the entire ARB just to renew the bushes?

They aren't available separately from LR. Are good quality replacements available and is it a common fix for specialists to replace the bushes alone?

Are the brackets bolted onto the arb? --------

That’s mental that LR don’t sell them separately!

Rimmer Bros list them from Polybush.

Thanks - I'd rather not have polybushes though. I'd like to retain the cushy smushy ride quality. --------

I would normally 100% agree when it comes to bushes and avoiding poly bushes but am not sure how much difference it’d make on the anti roll bar.

If genuine ones are available though, that’s 100% the way I’d go
