Not in the place where you have drawn it.
There is often a series inductor, to "extend" an antenna that is physically too short. Often combined with a shunt C.

This come from the theory. Small (or short) antennas are capacitive.
So, for impedance matching they need an inductor (or more inductors) to "tune out" this capacitance.

That was my explanation in #2. But they have a shunt L, not a series L. We don't know what the internal design looks like, so I have no idea what they use this shunt L for. There is a tap with some shunt inductance to ground for PIFA-type designs, but I don't know if that applies here.
Yes, series inductor is more convenient, but the matching can be done with almost any configuration.
These chip antennas have awful internal impedance which require unusual matching typologies.
