Oh no, you didn't come off as rude at all.
And it's great you care for your Toad so much. I've never had a toad before, so honestly I don't know and plus, my frogs are like a inch and a half, so all I have are roaches and ants. I'm still learning how to culture flies, so until then, that's their main diet. The occasional baby pill bug here and there, but my culture is new, only one or two females have produced offspring.
But what I was trying to say is, if your not sure, whether or not a super worm can eat through you're toad's stomach, then it's best not to feed him them until you are sure. Even if someone does tell you they don't but your still skeptical, then you don't have to.
Some people say sometimes you have to learn by trial and error and you said you've kept and fed toads super worms before. And because you're asking the question, I'm assuming they never ate through your toad? If so, then the same should apply here, but again if your not sure, you can always not feed them.
Culturing roaches is pretty laborious sometimes, but the result is worth it. I breed small roaches though and feed the even smaller babies/young adults to my frogs. Well, it's not so much a culture, as it is just a boy and girl roach I happened to find and bred by accident lol

Have you tried also feeding him wingless fruit flies? Although he'd probably need a dozen of those to be full.
And also, if you buy crickets, you can probably culture them yourself, there's plenty of info on the web and I think here as well, and that way you won't have to buy as much, if any.

It's how I learned to culture pill bugs, but they're rather easy, since they don't jump or anything and is currently how I'm learning to culture flies.
