If you could snap your fingers and have your type hints update to match your code, it wouldn’t get in the way of your work.

Hyperbolically: You have to be able to edit code at the speed of thought - whatever it takes - or else programming languages cease to be a more useful tool than just thinking.

If you type slower than you think, or can’t do the type-hint-based textual translation as quickly as you think, then… yeah - it’s not good for you.

The advice I’d wanna hear for myself is: just get better. But the advice I’d give to my coworkers is: have explicit domains where you’re able to do whatever is most efficient and effective, and then when you hand off data to the next subsystem - obey a contract. A schema. Be that type hints or a .proto file or a database schema or an API. Doesn’t matter.
