does rain typically leave as runoff where you're at?
depending on the topography of the land you're on, you might consider mulch pits. similar to what you initially proposed: dig a hole, fill it with mulch, plant a tree just downhill of the pit instead of in it. probably not as effective as more extensive earthworks, but quick and easy and capable of improving things substantially.
olives' home territory is dry and rocky, so artificially creating those conditions may just make them more vigorous.
Why do you think the fig didn't make it?

I've read a 10 year cycle of coppicing keeps them young and productive indefinitely, with the only real drawback being that mechanical shakers can't be used to get the fruit down for harvest.
If you're only managing one crown, you might cultivate ten stems from it, cutting the oldest one each year & leaving one new waterspout from each year's crop of shoots.
How is that done?
The soil here is rather alkaline so I'm not sure about lime. I'd like to gather as much water as possible in the winters. Sometimes there is quite a bit of rain in the winters, and sometimes they are sparse. For example this year there were 9 inches of rain in January, and that was about the only rain for the year.
