I've mostly driven in battery driven Stealth mode but recently a few longer trips have taken me into ICE Stealth mode (i.e., battery drained, engine on automatically) in around town driving.

When in battery mode, the response to flooring the "gas" pedal from a dead stop is 1.) a normal start (because the residual battery is being used apparently), then 2.) a quick drop off in acceleration (because it seems the engine has not been able to spool up) and 3.) finally the "roar" of the ICE and a reacceleration.

Is this normal or does my engine need some adjustment? I also notice this in Sport mode (with a charged battery); the engine seems to kick in too late when attempting maximum acceleration.

This has not been my experience. I drive in that mode pretty much every day including a long climb up a steep San Francisco hill on the way home, and there is absolutely no difference in response from the car between running on battery alone and running in charge sustaining mode (Stealth + motor running). Sounds like there is something you should look into. Either the engine is not coming up as fast as it should, or the computer is not firing it up fast enough, or the generator (which doubles as the engine starter) is lagging.

I have noticed this a lot.. I only drive with the engine on.. averaging 40mpg for the last 2k miles..

When the engine shuts down at stops it takes a while for it to get back up.. so I will hold the brake and push on the gas pedal a few times to kick the ICE back on and then launch..

overall the car is detuned to death.. even on a slippery surface its hard to break the rear wheels loose with trac off..

I'd think, this is intentional, to not harm the tires, but on rainy surfaces, mine for sure gets corrected by ESP

You really won't put the whole torque to the stationary wheels...

If I am taking the traction control off by pressing the button for 4 seconds I am intentionally trying to destroy the tires...

let me put that 1000ft lbs of torque to good use!
