I see that the first image you linked is from an ebay listing for parts (I stumbled into the same one in my searching), is the bottom image your actual device? Or another one you provided for reference? It would help to see what you're actually looking at if possible.
I pulled up a YouTube teardown of the Versa 2 and grabbed this image of the motherboard to reference.
It does look like an inductor and if the bottom image in your post is of your actual device, then it's possible it's damaged. You can test those at least on a very basic level by seeing if there is continuity through it with a multi-meter (there should be, or at least very low resistance).
I tried to see if I could find a datasheet for this chip to see if it recommends anything specific in the surrounding circuitry, but not finding anything specific.
How was your Versa actually damaged? Inductors rarely fail because of liquid damage, which sounds like it might be the case if you were cleaning up corrosion.
Update because I can't help myself:
Here's a different angle from that video where you can see the sides and this does not say inductor to me. I left some more info in my comment below, but I am more likely to think they are in fact mosfets or other tiny packaged ICs. But they could still be inductors, it's hard to tell with any of the images I could find.

@redamada really herd to see but it does not look like an inductor. Not saying it isn't, but the order on where it is located and how it is soldered looks odd. I wonder if it is a Diode or even an FET. 2nd picture, bottom part looks damaged. Is there any way you can zoom in on the component above it. Do you see any markings on it when you use a microscope?

@redamada since this was converted from another question, can you verify that your fitbit is a Fitbit Versa 2?

Yes, it's damaged. Yes it's a Fitbit Versa 2.

Without markings on the device, service data, or very clear photo of the part and connections to it, it is not possible to tell what that is or even guess.
However, it does not appear to be an inductor based on the size.
