Both Leica T Typ 701 and Leica X Vario have APS-C sized 16.0 MP resolution sensors so sensor size and resolution is not a differentiator between these two cameras.
Below you can see the T Type 701 and X Vario sensor size comparison.
Sensor Size and Resolution Comparison image of Leica T Typ 701 and Leica X Vario Cameras
Leica T Typ 701 and Leica X Vario have almost the same sensor size, so neither of them has any significant advantage over the other in terms of providing control over depth of field when used with the same focal length and aperture.
DxOMark Sensor Scores
DxOMark is a benchmark that scientifically assesses image quality of camera sensors. It scores camera sensors for color depth (DXO Portrait), dynamic range (DXO Landscape) and low-light sensitivity (DXO Sports), and also gives them an overall score. Leica T Typ 701 and Leica X Vario sensors have been tested by DxO and the results show that X Vario has a better overall score of 78, 3 points higher compared to T Type 701's score of 75.

Sensor size sets the circle of confusion, so it drives how much depth of field each
of these bodies gives you at a given aperture. You can calculate it exactly for the
Leica T Typ 701
or the
Leica X Vario ,
including hyperfocal distance.
