do London dispersion forces have high polarizability?

polarizability has more to do with the size of an electron cloud or the charge on a polarizing agent.
when looking at two nonpolar molecules with only London Dispersion Forces CH4 and CCl4, the CCl4 would have a high er boiling point and therefore a stronger bond than CH4 because it is more polarizable than CH4

London Dispersion Forces describe the interactions of temporary induced dipole induced dipole. The ions' or atoms' electron clouds themselves are polarizable, causing the LDF to be stronger or weaker but the LDF itself doesn't have high polarizability.

Molecules with just London Dispersion forces do not have polarizability, as they are nonpolar. These forces are present in all molecules, even nonpolar ones.

London dispersion forces are weaker than the other intermolecular forces and therefore does not exert high polarizability
