This kind of typing in TS is used mostly for getting dynamically typed Javascript codebases under control.
I did this once for a state management library that was considered "impossible to add types to" by the authors themselves, and thanks to this I found several bugs in the library itself, and in our own codebase, due to subtle incorrect usage.
Just the fact that we got autocompletion across the whole app was worth the effort. Even the engineer that was against it ended up praising it.
I'm not the kind of person to say this but: maybe some things are not for everyone. Some people just have different interests and skills. Complicated things aren't less worth just because someone in the team can't understand them.
