I'm not aware of one that meets all of those requirements. However, you may be able to feed an NTSC LD player out to a video recorder capable of NTSC playback on PAL via S-Video, then capture the PAL output. It doesn't matter if the video recorder can play tapes or not as long as the S-Video input works and it can output to SCART or similar for capture.
The thing with this is that you're going to end up with a capture that is not the same as the original source. I don't remember all of the ins and outs of doing this as I haven't had to in nearly 20 years, but one of my recollections is that NTSC source material is typically recorded for a 60Hz sync, whereas PAL is usually (Brazil aside) recorded for 50Hz sync. You'll get NTSC to play back on PAL using this method, but there are issues with syncing video frames correctly in this scenario.
Just find a video capture card that can handle NTSC directly and connect your source straight to it. It'll simplify things greatly.

From what I recall, virtually every laserdisc game ever released used NTSC as its on-disc video format. There may be exceptions to this (the Web Picmatic games such as Zorton Brothers *may* be an exception, though I don't believe so), but I'm not aware of any.
Assuming that the above is correct, just do straight NTSC capture. There is no advantage to converting the video to PAL - unless you're converting to the 60Hz PAL-M format used in Brazil, there are going to be sync issues with frame (and therefore VBI) timing. Even then you're going to be changing the video from the format it was originally stored in as (IIRC) PAL was 625 lines total.
