In this particular instance, it's that none of the offers are viable. Either they're expecting a minimum of $150 or so, or they're expecting you to use a specific payment method that I am not comfortable with using.

If non of your criteria matches a offer, sure, that's not good.
You could try and create a own buy order and see if it gets fulfilled
I'm not sure how to set up that sort of offer, and I'm unsure if it's a good idea for a first-timer, is it?
It isn't very complicated. You just have to choose if you want to buy or sell, your payment method and the trade amount. In the advanced settings you could set a trade range or a higher percentage for the collateral.

But what about the escrow thing? From what I heard, most DEXes use that and I have no idea how the technicalities work for the person making the offer.
What's with the escrow? You have to lock it before you can publish your order. Therefore a LN invoice QR code will be presented, pay it with a compatible wallet and you're good.
