You're right—I didn't mean to suggest they've never sued competitors. Some companies are just known to be litigious—I've never put Apple in that bucket. (And maybe I have blinders on. It's certainly fair to blame me for being biased.)

Because Apple didn't sue Samsung over IP theft. They sued them over copyright infringement.

It was actually patent infringement.

Copyright infringement is a sub-category of IP theft. Other types of IP theft include trademark infringement, and patent infringement.

Sure, I guess. But I think people reading this thread are drawing a line between "Copying the publicly-visible IP" and "Inducing employees to walk out with trade secrets in hand." No one at Samsung was facing prison time. People at OpenAI very well could.
