rr is a gdb protocol server. By default, rr also executes gdb client and automatically connects to server, but you can use -s PORT option to run rr in server only mode.
As I understand, after rr is running in server only mode, you can connect to it on gdb with "target remote :PORT", or on LLDB with "gdb-remote :PORT". I haven't tested this, but it should work as long as LLDB implements gdb protocol in a compatible manner.
