RE: Meaning of the term "Boot"
The heavy phase (water) will collect here and give your process control a lower holdup time (for the part in the boot).
Usually a company standard will include how to size it. E.g. Shells DEP 21.22.05.12 specifies that the minmum length of the boot is 1 m. The actual length is defined by control needs also specified in the company standard.

RE: Meaning of the term "Boot"
But I think that what you are after is what I would term a "shroud". At the inlet to the suction of a sump pump it is sometimes done that a reducer or specially shaped cowl is installed to allow gradual acceleration of the fluid.
I would also not be surprised to hear a deepened section of a sump (where the suction pipe would be) called a boot.
So there are many things that could be called a boot and if I were in your shoes (or boots!) I would go back to whoever specified "Liquid Boot Required" and ask for specifications of the boot.

Thanks for the efforts in bringing clarity to Mortens' reply.
I will give little more inputs. See if any of you can bring more clarity .
Supplier says the boot is
(total pump's length + Distance betn bottom of the sump to underside of the pump)- ( Sump height + manhole standout or height of the nozzle provided at the top of the sump)
By this formula I am no way able to understand what this term " boot " physically mean !!
It could be a shroud or pipe , but what role it plays in functioning of a pump ?
As regards to cavitation / NPSH the supplier has given the data on minimum submergence.

After sending my previous post I remembered that I have seen sump pumps where there is a small reservoir installed in the suction piping to ensure self-priming. Perhaps this is what they are after? Ask them for a drawing.

Another definition (petro eng) for boot is "surge column". Meaning a large-sized pipe of sufficient head able to absorb liquid surges.
