I’m not sure why it’s annoying, as the OP says in the original post there are at present no Caseta switches designed for the control of LED drivers. That’s not a smartthings issue, it’s a Caseta issue. You can verify that with Lutron support or see their selection tool:
So the next step for the person who started this thread was to consider alternatives, and that’s what people were helping with.
If you only want a Caseta switch, therefore, you’re out of luck until Lutron releases one. 
If you’re willing to consider other alternatives that work with smartthings, then see the recent community FAQ:

(BTW, as I mentioned before, I use Lutron Caseta switches in my own home and like them very much. But I’m not using them to control LED strips.)
