I think interlocking bricks may work if you use very little mortar between the bricks.
But with earth bricks, an earth mortar of the same material as the blocks are made from, and about 1 inch thick when the block is laid, will be very good.

You may find somebody who can make your bricks for you, if you have cash.
Otherwise make adobe bricks, which take a bit longer.
Either way, earth bricks are hard work.
I know I have built many homes with them.

I did a quick search and found the same things you did. China / third world is the place to buy one. MAYBE you could locate a used one in the U.S. ... I wouldn't know where to ask ???
Alibaba itself I believe is up front (honest) each seller is the question. They have ratings like ebay and I think I would use my judgment after contact, to determine if I want to send them my thousand dollars or not... My biggest concern would be the shipping. I would want a locked down price up front. At the least , delivered to the nearest large town.

Sand Castle Holds Up A Car! - Mechanically Stabilized Earth
When I was thinking about using sandy soil in earthbags and didn't want to risk wearing and tearing, I looked for screen materials as mentioned after the 4:00 minute mark in the video above. (That homework led to finding basalt materials formed as rebar, mesh, fabric, rope for various purposes. I may use a basalt mesh or fabric for a project.)
Your area being low in clay, might produce the effect you're looking for by making a thicker wall by layering something suitable about every foot or two. If you try dropping different shapes of heavy weights on the test bricks, that might help find a way to combine materials to achieve the strength you're looking for.
Forgive the lack of tech jargon. I'm nowhere near being an engineer, and learn by seeing what goes boom or not :)
