If I run OPTIMIZE on a Delta Lake table, will it prevent me from time travelling to a version before OPTIMIZE was run?

No, you will still be able to time travel to versions previous to the OPTIMIZE command.
OPTIMIZE is just another transaction like MERGE, UPDATE, etc.
Check out these docs to learn more about retention periods and the VACUUM command.
