But isn't the primary supposed to be aerobic fermentation in the beginning? That is why oxygenation is necessary right?

and it just seems odd that within a few hours of cracking the lid to take a look, the blow off tube started bubbling one every 10 to 15 seconds or so.

The next morning the blow off was bubbling about once every second or so, full blast.

I guess it could be coincidence, but I have had the same thing happen multiple times, and every time with dry yeast btw, no starter, pitched dry.

I have never had it happen with liquid yeast.

I don't know if you saw my post, but what's wrong with the explanation that your lid wasn't on tight before you took a look?

That's a real possibility since the OP saw krausen when he opened the lid. Also, the mere opening and closing of the lid doesn't introduce enough O2 to make a dime's bit of difference.

O2 is needed during the initial phases of fermentation when the yeast cells are engaged in aerobic respiration while sprouting "daughter cells" during reproduction. After that, they run out of dissolved O2 and switch over to anaerobic fermentation (converting the sugars to alcohol). Once they go anaerobic, you don't want to aerate the beer.

Like I said though, there was pressure in the blow off tube, bc the water level in the tube was lower than the water level in the jug of sanitizer.

the lid was on for sure, it is one of those gasketed plastic lids, and the middle of lid bulges when there is pressure, which there was.

maybe it is the release of pressure that helps?

or it is just a coincidence of timing.

FWIW, I just had this happen to me an hour ago with my current batch. 24 hours after pitching, there was noticeable pressure change on my airlock, but not enough to bubble.

I took the lid off, saw a nice creamy layer of krausen forming, sealed it back up, within 10 minutes it was bubbling like crazy.

There's no reason you can't have pressure on your airlock/blowoff, while also having air leaking somewhere else.
