Hi,
I have checked the following documentation:
https://www.teamfdi.com/wp-content/uploads/USB-ICP-LPC2K-Master-Brochure-R11.pdf
The USB-ICP-LPC2K device is a third party product, currently, it is obsolete. It is an USB-TO-SCI device. I think you can order the similar product from the other manufacturers.
I have searched on Google with the key words" usb to uart dongle", you can see a lot of product.
Regarding the pin and Reset pin which can force LPC17xx enter ISP mode, I think you can press the button on the target board so that the chip can enter ISP mode after power-up.
Hope it can help you
