In you scenario you basically hand over the keys to your utxos to Boltz in exchange for an off-chain payment.
Boltz would have to spend the coins now, either cosolidate or single spend, so in a high-fee environment, they would likely charge you with the cost of moving the coins on-chain by subtracting a fee from you lightning invoice amount that you receive.
That is not how Boltz swaps work. They give you an address to send lockup funds to, then claim it with the preimage from LN payment. How you fund this lockup address is your problem.

I see, I was thinking about static address swaps from Lightning Labs, that's how they work. But the classical swaps yeah, its the clients job to publish the funding tx.
