Yes. The etymologist who tracked down the origin of OK as "oll korrect" was named Allen Walker Read.

The groundbreaking article authored by him is called The First Stage in the History of "O.K." He presents many examples that clearly support his assertion of the use of "OK" in the 1830s and 40s, and a couple of the quotes he pulled do show disapproval toward the abbreviation fad.

The earliest denunciation actually predates the first mention of "all correct" as the meaning behind OK. It comes from page 1 of the June 19, 1838, edition of the Boston Post in a letter to the editor:

"The present age is one pregnant with experiments...There is yet one other sect...who in their fondness for a brevity of writing, would discard every letter of a word, but that with which it commences.

"They extend this principle to speech, too—the glory in hyroglyphics—they rejoice in stenographics—but it is to this very class that I would send forth my denunciation—let it be said that it is a dangerous sect—men whom Caesar would have regarded with a suspicious eye...I mistrust them—let them come out freely and openly and show us that their cabalistic signs are not omens of evil..."

The following year, an article appeared in the Philadelphia Gazette reporting on the fad, and the New Orleans Sun reprinted the article on page 2 of their December 3, 1839, issue. But the editor of the New Orleans paper added his own introduction:

"HUMBUG.—It is laughable to observe what trash is served up for the edification of the Philadelphians..."

However, these are just two out of literally dozens of articles reporting on the fad around that time. In Allen Walker Read's other examples, the reporter either made no commentary one way or the other, or else found the fad "amusing."

In fact, Read points out that many newspaper writers joined in with the fad through their writing, offering up their own ridiculous initialisms that were never actually used in oral conversation. One example from the New York Evening Tattler being "W.O.O.O.F.C." ("with one of our first citizens").

Others actually were used colloquially, the most popular other ones seeming to be "N.G." and later "K.G." ("no go"/"know go"), "K.Y." ("know yuse"), and O.F.M. ("our first men", a derogatory way of referring to self-important young upper class males, something like "yuppy" today).

If the subject of the word "OK" interests you, I highly recommend picking up a copy of Allen Walker Read's Milestones in the History of English in America. It's a collection of his scholarly essays, so it can be pretty dry, but about 50 pages of the book are dedicated to the etymological history of "OK" with lots of quoted sources beginning from its earliest written use in 1839. Many of his articles are available individually on jstor as well.
