@davids5 hello good sir, thank you again sir for creating another excellent driver so I didn't have to! Do you concur with my findings above?

You are welcome.
Good job unwinding it! I think I only tested IMXRT_LPI2C_DYNTIMEO (I only use the setting). Also this code is in other archs as well - so the fix may be far reaching.
I do concur. Kconfig should supply the values and the enables. All the default guard in code (setting defaults) should go away.
I also think the the value can be just timeout in us and a 32 bit value. That will give use us resolution and 4.29 S max.
ticks is also not a good unit. It needs to insure the value is 1 for the min us - but then it can be 10ms for 1 tick. (we use 1 ms tick)
So that should be addressed also.
What do you think?
BTW, I do see CONFIG_IMXRT_LPI2C_DYNTIMEO_STARTSTOP used
