There are more Amish in HOLMES COUNTY OHIO. THAN in Lancaster County Pennsylvania!
We visit a local one about 1/2 hour to the NE of us in Middlefied, OH. If you drive a little further east there is a great little general store that has a lot of the old candies, toys, etc called “End of the Commons General Store” on the corner of OH 534 and Kinsman Road in Mesopotamia, OH.

Middlefield has the usual fair - cheese factory, furniture stores, a couple of nice flea market locations, etc. Not too far off I90, but you will have to drive a bit to get properly out in the “boonies”.
The other location I’m familiar with in Ohio would be a triangle between Millersburg, New Philadelphia, and Canton. This one may have easier access and more places to go from the interstate. I like the first more because of the General Store’s charm.
This map kinda highlights both Ohio areas:

Course I grew up in southern Indiana - so if you are head through on old US 50 it’ll take you straight through historic Vincennes (site of a historic battle during the revolutionary war - George Rogers Clark fame put up as many standards as he had men).
Then keep going east on US 50 through Daviess County once you get past Washington (~20 minutes east of Vincennes) you’ll be in Amish country there.

Given your headed toward NY it’s likely that Middlefield will be the closest to your route if your going to head through Eerie on 90.
There is a large community east of State College Pennsylvania. Lots of Old Order
Amish & Mennonite.
Freepmail me if you are interested as we work with about 600 horse & buggy families.
Shipshewanna, Indiana. Very popular site. Lots of food shopping and entertainment. All G rated!

Amish and Mennonite Food Stores in New York
And there's The Windmill Market in Penn Yan, New York that may offer Amish crafts/food:
Stop and stay in the Murphin Ridge Inn in Adams Co. Amish style but not run by the Amish who live, farm and retail all around it. And, while you are out here, you can see the Serpent Mound. The most important archeological structure in North America:

The Amish community I mentioned is very near I-80, about 3 hrs West of New York City.
Heck, come to my town, Meadville in Western PA. Amish all around and you see them on a daily basis. My sister in-law is a Yoder Toter, and I about died laughing when she told me of transporting Amish and their goats in the back of her mini van.
Unspoiled? Charm Oh, and Mt. Hope OH. Berlin is one tourist shop after another.
There are no Amish run bed and breakfasts in Holmes county, but some run by Mennonites.
We stay in cabins built and run by a young man who grew up Amish. Look up Simple Life Cabins on Facebook if you are interested. They are located on a back road among the most conservative Amish.

Excellent cherry wood furniture.
This is probably the wine talking, but I have taken a strong disliking to the Amish and their practices when it comes to puppy mills. Say what you want, but I have seen some bad sh-t and I love dogs so I will not give the Amish respect. Other than that I have nothing else to add.
Some years ago there was an Amish community in Barnesville, OH.
I think your problem will be finding among the many (hundreds) of so-named “Amish” towms stretching from the Mid-Altantic states into the MidWest is which ones remain authentically Amish and which ones have largely “English” owned property that has built up around the Amish farms, and is there to make a living off the tourists.
There is a growing Amish community around Belleville PA in Mifflin County (off US 322).
