I'm not sure that connotation is all that present in the way it's commonly used, but I'll grant it. However, like the other person you responded to has said, "slop" already had that meaning, because it is the low-grade cattle feed. So If both "AI slop" and "goyslop" carry these shades of meaning, it would not suggest one descends from the other, but that both descend directly from "slop".
That's maybe true, but "goyslop" was specifically referring to vapes, processed food and tiktok. Then shortly after people started calling tiktok "slop" and ai tiktok "ai slop".
I think its a stretch to declare there is zero relation considering how much internet language originates from 4chan.

That doesn't sound very specific, that sounds quite broad. Looking around posts up to 2023 I can see the word used for just about anything, including HDMI and Disney. Honestly, this says to me it's just used as synonymous with "slop" in the broad sense, with no added meaning.

There's no zero relation. The relation between the two terms is just not parent-child, but fraternal. Both simply inherit their meaning from "slop". "Slop" already has connotations of cheapness, low quality, high quantity, and cattle feed, and is a word that has existed since Old English. There's literally no reason to think "AI slop" is descended from "goyslop". At best someone heard the latter and by analogy coined the former, but given that "goyslop" had already been coined by simply prepending a modifier to "slop", there's not even any need for that explanation.
