Hi everyone,
The issue got resolved with the new Apple adapter.
Thank you for your feedback.

I have seen this issue on my touchbar Macbook Pro using Apple's USB-C AV Adapter and a Dell monitor with 3840x1600 native resolution. The Apple USB-C AV adapter only supports 30Hz which is pretty bad for good mouse operations, but AI also introduces a lag.
I was able to workaround this issue by purchasing a USB-C dongle that supports 60Hz. This doubled my refresh rate which helped all apps and also appeared to have fixed the issue with AI. The dongle that worked for me was made by Newpower(3-in-1 Type C Hub). Make sure it supports 60Hz.

I was able to work around this issue by using the above dongle instead of Apple's USB-C AV Multiport adapter. Apple's adapter is restricted to 30Hz for my dell 38" monitor, this dongle can do 60Hz.
None of that explains why the lagginess affected Illustrator, but not other Adobe apps, but I can confirm that this adapter did fix the problem on my machine.
Apple has come out with a new adapter that fixes this issue. Unfortunately, the product name is the same.
I confirmed that the 60Hz version MODEL A2119 EMC 3279 works fine. The offending Apple dongle is MODEL A1621 EMC 2877.
