Specific to the leads being changed inside the controller.. I agree but the only way to correct is to either get inside the controller or the motor end, or switch the leads in-line .. correct?

Yes, as far as I see it.
Somehow, somewhere those two wires need to be swapped.

The important thing is that you now know what two wires need to be swapped.

My e-bike had a reverse firing order so two phase wires and the corresponding hal sensor wires needed to be swapped as two pairs.

Your motor having two hal sensor wires swapped is just a dirty trick.
That can be really hard to troubleshoot, even if you take your motor apart to investigate.

This is my motors guts showing the four hal sensors (three for the phase wires and one for the speed sensor),..

The fourth hal sensor is the speed sensor that monitors the speed magnets on the motor casing,..

Having two of your hal wires swapped would be pretty hard to determine because you'd need to know what phase wires they are paired with.

I would assume that "H1" would be the first sensor in the firing order, and would be paired with the first phase wire in the firing order in your controller?
Then you'd have to try to figure out the firing order of the controller by probing the circuit board to find out which phase wire is first?

I going to fix these two EBC bikes and sell. Then I am doing the same as you.. building my own.

Start with a normal motor that doesn't have the damn wires all mixed up.

POeBiker, You are correct, the phase wires were also swapped. The challenge for me is that changing the settings in the display impacted the wire configuration I had to try many, many configurations, with many different results. For those who are in similar situations ( Electric Bike Company EBC bike needing repair), I suggest this.
1. Make sure the generic controller and display are compatable with each other. EBC's display is KTLCD8HU. I could only find KTLCD8H which has different graphics and a much different look.
2. The generic 5-1 controller cable will have different male/female brake connections ( I don't care about brake cut-offs, not an issue)
3. The 9 pin cable to the motor will need to be rewired. I bought an extension and did the rewire, (see pick) showing the swaps that got my bike running along with controller settings. Beware Changing WILL affect the other.
4. My bike runs full throttle 28 mph on all levels. ( this should be correct with programing change
5. PAS does not work. The display LDC8H doesnt' show the same graphic for PAS as EBC's display LDC-8HU (Still trying to figure out.)
6. The settings in LDC8H are different than EBC controller LCD8HU. you will have to tweak them.. Which I am still doing. Will update when I figure it out.
