Inductor for current is like capacitor for voltage. It will continue to push current when it drops and resist current when it rises. In no way it can restore missing half wave.
In line conditioners that usually sold everywhere, if you ever disassembled one, you will see a relatively small inductors on each wire or a common mode choke with capacitors before and after. Somethimes semiconductor surge protectors (varistors) added. This circuit is mostly for supressing noise in power line and cutting noise that could come from devices you connect to it, and if it have supressors nothing more. In no way inductors and capacitors used could store enough power to restore somehow missed half wave. It is just a HF filter, usually designed to cut frequencies higher than 2kHz, nothing more.
Just tear down one and see that by your own eyes. You could even easily measure frequency characteristcs if you have a tunable frequency generator and multimeter.
Line stabilisers, are another beasts that switch windings when grid voltage drops or rises, to keep output in limits, they can't restore missing half wave too.
No one said the inductor will restore a missing half wave - I said it responds in a certain way putting out energy after input power goes away. All it takes is a fraction of a cycle time to do that, but it allows any battery fallover power source being activated to drive to any DC to AC generation circuitry. Which can be activated very rapidly, being semiconductor based, and within a fraction of cycle time.
I believe now you are a technician parading authority, so enough of this.

Of course it can. But should not. Imagine, mains power disappear at the bottom of AC sine. You had -110 V on the hot wire at that moment. Then, you start DC-AC converter that starts from top of AC sine at +110 V on the hot wire.
Guess, would be your devices glad if they suddenly get a surge from -110V to +110V "within a fraction of cycle time.". What if you have some inductive or capacitive load on the UPS output?
That is why there is a delay in switching from mains to battery or vice versa in cheap UPS.
Just take oscilloscope and check how that works if you are in doubt.
