I disagree (not with the general rule of which claim came first, but with your
example of it).

To claim no losing chances, you should (or have to, I'm not sure) stop the clock
to involve the TD. If you stop the clock to make the claim and your flag has
fallen and your opponent doesn't notice that the flag has fallen, it would seem
to me that it would be unfair for the TD to allow the claim. The TD should deny
the claim, regardless of the position since you DO have a losing chance (your
flag fell, you have technically lost, even if your opponent has not yet noticed
it). He should say, "You have a losing chance, play on.". He should not tell why
you have a losing chance, it is up to your opponent to see why.

This would be the fair thing and would correspond to other rules. For example,
if you mate an opponent and you hit your flag and your flag falls while hitting
it, your opponent can claim that you lose on time, even though it "appears" that
he is mated. The clock takes precedence (as long as your opponent notices it).

If your flag has fallen and you have to change to a digital clock with delay,
the TD should claim that "You lose.", even if your opponent does not notice the
flag. Why? Because there is no time left, hence, the TD cannot place 0 seconds
on the clock.
