Just had the same problem. The naming is a little unconventional in this case.
For reference: You can find the right setting by simply looking through the source code:
https://github.com/dolphin-emu/dolphin/search?q=%22Manual+Texture+Sampling%22
will give you this line:
new GraphicsBool(tr("Manual Texture Sampling"), Config::GFX_HACK_FAST_TEXTURE_SAMPLING, true);
and looking for GFX_HACK_FAST_TEXTURE_SAMPLING
( https://github.com/dolphin-emu/dolphin/search?q=GFX_HACK_FAST_TEXTURE_SAMPLING ) will in turn reveal
const Info<bool> GFX_HACK_FAST_TEXTURE_SAMPLING{{System::GFX, "Hacks", "FastTextureSampling"},
which tells us that the setting is FastTextureSampling
[Video_Hacks]
FastTextureSampling = False
is what you're looking for ^^
