Good stuff 
I haven’t used it, but it looks like it’s got the right design for what you want. I learned from Lae’ti’kol that protection is very effective done in layers, combining all sorts of wards, shields, thoughtforms and obfuscations. If one thing doesn’t catch something, the others will. It ends up being, ime so far, that the only thing that can get through is another directly intentional, skilled human, as nothing else does or can disrespect boundaries and free will, on this planet, like a human, and then it’s a battle of wills.
The disadvantage for them is, if a human pops up in your field, you will also know who it is as the connection goes both ways.
Hexbreaking, in this case seems like swimming against this current created by her prayers, like she’s said “…and let nothing get in the way”… so work that diverts reverses the flow, dams it, whirlpools it into the Earth, dries it up so you can carry on getting in the way would be nice I think diverting it to another person, like, fixing or strengthening the relationship of other people you know might be easier?
Kind of like using a decoy as a protection mechanism, so the mother’s magick acts on the decoy not the original.
And then the binding can be worded and intended with no harm, just “she will not work for this”.
If you’ve seen Keteriya’s tutorial to implant thoughts into other’s minds that looks rather good and doesn’t need an entity. I intend to try that myself pretty soon.
