get_woocommerce_currency()

You need to override the active currency temporarily:

function ___return_currency_USD() {
	return 'USD';
}

// Temporarily set active currency to "USD".
\add_filter( 'woocommerce_multicurrency_override_currency', '___return_currency_USD' );

// Create order programmatically.
$logger     = \wc_get_logger();
$product_id = 10;
try {
	$order = \wc_create_order();
	$order->add_product( \wc_get_product( $product_id ), 1 );
	$order->calculate_totals();
	$order->save();
	$logger->log( \WC_Log_Levels::INFO, 'Order total = ' . $order->get_total() . ' ' . $order->get_currency() );
} catch ( \Exception $exception ) {
	$logger->log( \WC_Log_Levels::ERROR, "Cannot add product ID ${product_id} to the order." );
}

// Stop overriding currency.
\remove_filter( 'woocommerce_multicurrency_override_currency', '___return_currency_USD' );
