I wrote up an entire response and then decided to check for myself what the EULA (End-User License Agreement) says about using its sounds:
B. Except as otherwise indicated, you may use the Apple and third party audio file content (including, but not limited to, the Apple Loops, built-in sound files, samples and impulse responses) (collectively the “Audio Content”), contained in or otherwise included with the Apple Software, on a royalty-free basis, to create your own original soundtracks for your film, video and audio projects. You may broadcast and/or distribute your own soundtracks that were created using the Audio Content, however, individual Apple loops, audio files, sound settings, samples and impulse responses may not be commercially or otherwise distributed on a standalone basis, nor may they be repackaged in whole or in part as audio samples, sound files, sound effects or music beds.
Essentially they're saying yes, you can. Apple purposely created Logic for the creation of music & sound & whatever is in your head/heart/soul, so for them to make their Jam Packs available to the public for use in a program that is specifically for creating but restrict how & when & where you're able to use the works & performances you create wouldn't make much sense, at least not to me. As long as you're not trying to make money off what they've created by passing it off as your own or redistributing it for your own profit or benefit (which I don't think you're doing ), you're completely within the bounds of the legal limits they put forth in their EULA.
