Can anyone recommend an inexpensive isolation amplifier product, either a chip or a module, with an accuracy of 1% and DC signal sampling?

You can refer to Toshiba's TLP7820, Avago's ACPL-7970, etc. You may need to choose an accuracy of 1%.

If the speed requirement is not high, you can also choose the isolation solution composed of APC chip and PAC chip, GP9301+GP8101 will do.
