I want to get a bottle holder for my bike.
It has no pre-drilled holes for the holder.
I found some that clamp on but not sure if they would work with the wide tube that I would need to mount it to.

Get a clamp-on solution like the SKS Anywhere, Topeak VersaMount or Elite VIP.
As Nate W pointed out in the comments, make sure it doesn’t interfere with your cables.
A quick and dirty solution with cable ties and duct tape can work temporarily as well.
There are also bottle cage mounts which clamp to the saddle’s rails, for example the TacX Saddle Clamp:
I think a disadvantage of this solution is that you can’t slide behind the saddle on descents. They are primarily intended for time trial bikes.
There are a number of options here:
Get creative! There's lots more ways to carry water out on the trail.
Clamps, drilling, etc into the frame are probably not the best idea for maintaining the integrity of the frame and security of the bottle.
Using a strap on cage would likely be the easiest method. You should be able to ask a question of the manufacturer and get strap lengths to compare to your tube circumference and determine fit. It's quite common for bikes to have very large downtubes and I imagine it's common for strap on kits to come with longer than necessary straps, since they can usually be trimmed.
You could also get a quote at a shop to get holes drilled in the frame and threaded rivets installed and mount a cage. More info here. I've done this on both bikes that came with no mounts and as a fix on bikes where the threaded rivets from the factory became stripped (after drilling out the stripped factory rivets). This might be more expensive up front (labor from a shop) but allow you to use a much less expensive cage.
