Are people expecting Luke to die because the film is called The Last Jedi, or because it's expected?
Predominantly because the original trilogy was, beat for beat, a direct application of The Hero's Journey by Campbell. It's a recipe that works, and one which Disney have used time and again to multi-billion-dollar effect (check out the litany of Disney Princesses with dead parents).
In The Hero's Journey, the death (or otherwise insurmountable loss) of the mentor is what drives the protagonist into engaging with the story themselves. Otherwise the'd just be like "Hey, you're way more experienced than I am. Why aren't you taking care of this situation?!"
So basically it's expected that Luke will die if he trains Rey because that makes him her mentor, and mentors die.
Now, if Rey chooses to ditch Luke's training and go for a more balanced approach, Luke doesn't need to die at all. That counts as insurmountable loss for story purposes
