Analog buffer with op-amp at 0V input
That opamp (LF353P) only works to within 4 V of the supply rail, so won't work with the 1.5 V negative supply you show.
What you need is a rail-rail opamp such as TLV2771 -- see https://www.ti.com/lit/an/sloa039a/sloa039a.pdf
Depending on your high voltage, you may not need the middle 1.5 V cell. note that cells which are nominally 1.5 V will vary from 1.9 V (new) to 0.9 V at end of life. Thus your 9 V cell will also discharge to below 6 V.
