What I think is that it was used to reducing the output current, but it will also affecting the output voltage when it is in series with the input resistance of the next circuit, the final output will be as a voltage divider output, it is depends on how high the input resistance of the next circuitWhat is the purpose of R25?

Yes, I thought the symbol was labeling NI as V+, now I see that isSure you don't mean the non-inverting input?
Why so large?

use a 50k or 10k?My apologies, I completely forgot about the issue with discharging the 10 uF
thru the input when supply is shutoff. Leave R19 in.
