The frei shuls often use their own non-Orthodox authors, including female “soferets”, to write their sifrei Torahs, which undoubtedly are pasul.
If a real Sofer (i.e. Orthodox) wrote a Sefer Torah for them, something I cannot understand how they can justify in the first place, I would certainly hope he pasuls it during the writing from it being a real Sefer, as the recipients will undoubtedly mistreat it in many cruel ways.
