Question about Hidden Step

Hidden Step is a trait of Firbolgs in MoTM, which says:

Hidden Step

As a bonus action, you can magically turn invisible until the start of your next turn or until you attack, make a damage roll, or force someone to make a saving throw. You can use this trait a number of times equal to your proficiency bonus, and you regain all expended uses when you finish a long rest.

I think that "force someone" is an interesting choice of words.

• "force" would suggest that a self-inflicted saving throw (like willingly walking into a Spirit Guardians aura) wouldn't count. It's their choice and I didn't force them to.
• "someone" would suggest that creatures that are not people would be excluded. Including beasts, monstrosities, constructs, etc. They're not someone, they're something.That's why the most commonly used word to designate enemies in the rules is "creature" and not "someone"...

Am I overthinking this?

Yeeaaaaahh you're probably right. Still, you gotta admit that the wording there is a bit ambiguous.
And it would absolutely not be the first time that a set of rules isn't explicit about what it does (ref. the topic about Chainlock).
But yeah, I'll admit this interpretation is bit far-fetched :)
