The target computer does not have a usb port
The target computer does not have a usb port , There is no way to use Tinypilot
Is there any solution?

Unfortunately, there's no solution in this case. TinyPilot needs the target computer to have a USB input port.
What sort of computer is this?

I highly doubt any adapters from USB to PS/2 for these older computers would be compatible with the composite device. It might be possible to create such an adapter with TMK/QMK or more likely using a microcontroller directly.
I thought this was an interesting problem so I did a bit of research.
Pricey option that may work, but no guarantees, you'd definitely want the TinyPilot power/data splitter because odds are it doesn't expect very much current draw by the keyboard.

https://retrocomputing.stackexchange.com/a/7723This guy has implemented the microcontroller route for converting USB to PS/2 with some caveats (no multimedia keys, which most PS/2 only devices probably didn't understand anyways).

Thanks for those pointers, @dragon788 !
I wasn't aware of the Adder device. That could be useful for customers with a hard requirement on PS2.
