No, it's because it's all a part of the nervous system and all of the sensory organs at one point started in the same place. As species evolved, the sensory organs changed/moved as much as they needed to to cause the organism to survive and be able to reproduce.

At no point did evolution think gee, can't put the eyes too far away from the brain, that'll sure take too long to see things! Evolution doesn't think. It's blind luck.

And compared to the brain's processing speed, any latency from distance to the sensory organs is miniscule

"The researchers found that, after controlling for sex, age and temperature (it turns out your nerves are quicker when you’re warm), there was a 0.27 m/s decrease in the conduction speed of one of the leg nerves (the sural nerve) for each additional centimetre in height." https://mindhacks.com/2009/05/19/tall-people-have-slower-nerves-sensory-lag/

.27 ms per centimeter is basically negligible.
