His whole invisible hand metaphor is about society advancing as a whole from agents acting in their self interest.
It's more likely a sincerely held belief than an attempt at misdirection.

That theory is predicated on the market being composed of buyers and sellers of broadly similar financial power. This is no longer the case in most markets, certainly not in the UK as far as ordinary people or most small companies are concerned.
Don't get me wrong, a budget that cuts taxes without cutting spending is no good. But the idea that what happened was a direct consequence of that doesn't make much sense as it had been telegraphed a long way in advance, giving the markets plenty of time to adjust. The central bank changed monetary policy a day before the mini-budget, and changes in that are kept secret until the moment of announcement. Additionally, UK spending has since blown through what the mini-budget would have created without any sudden market turmoil.

Regulators failed to anticipate the dangers that borrowing by pension schemes posed to the stability of the UK’s financial system, according to a parliamentary report into the turmoil that hit the gilt markets following Liz Truss’s disastrous “mini” Budget in September last year.
Pension schemes suffered multibillion-pound losses after they were forced to sell assets to ensure that complex derivative-linked strategies — known as liability driven investments (LDI) — did not implode when gilt yields jumped as investors rejected the then prime minister’s economic strategy.
Also, Truss is basically correct that the UK needs more growth. Disagreeing on her tactics is reasonable, disagreeing on her goals isn't. She was unfortunately attempting to create growth from a position of weakness: in a party that didn't want to do anything hard like cutting spending, and with a fragile/over-leveraged financial sector.
