With my intent to paint alla prima using Liquin Original medium with oil paint on Ampersand Gessobord, are there any problems combining OMS with Liquin Original and including an oil color to seal the India ink and tone the panel?

That should be fine as long as the ink is not applied so
thickly that it is a glossy coating. Honestly, I would use water soluble ink
rather than shellac-based waterproof ink. Either would likely work fine. Make
use that you are not using a dye-based ink but rather one with carbon black as
the coloring component. There may be some bleed with dye-based inks as some of
the dyes can be sensitive to organic solvents AND, many of them are not
lightfast.

Thinking about it more, make sure that the gessoboard is
absorbent enough to take the ink well. Inks are so fluid that I would want to
make sure that the ink did not bead up. Likely this would be fine. If it turns out
that the ink does bead, I would just switch to the Clayboard from the same
company (not because of brand supremacy, nor against it, but because you appear
to already have justified faith in the company).
If you go the Clayboard route, you may want to cut the absorbency
of the panel after the ink stage but before the proper oil painting stage. In the past, I have
isolated the underdrawing and lessened the absorbency of such a panel using a thin judiciously applied alkyd medium rubbed
on using a rag in a circular motion. This should be continued until there is no visible medium on the
surface and it appears satin. In a way, this is a modern adaption of the oil
based imprimaturas of the Renaissance (although those were usually, but not
always, pigmented. However, you mention toned so, perhaps, you intend to apply a pigmented coating anyway.
I hesitated to mention the above procedure as it is very easy
to overdo it an create an overly slick surface; but if properly done, the
results are superior to applying shellac or a spirit varnish since the isolation
layer would be insoluble in the solvents normally used in painting and even
conservation.
An additional precaution is that this methods should not be
used if one plans on leaving any part of the panel uncovered by opaque or at
least semi opaque paint. Even though alkyd mediums do not yellow as bad as some
media, they do yellow and one would not want this to remain exposed to discolor
over time.
