Alteration of function by rational approaches can be achieved through single-point mutation, exchange of elements of secondary structure, exchange of whole domains, or generation of fusion proteins
Whereas irrational design uses random mutations to gain insight into the functional capacity of specific residues or domains, which may then be further manipulated by rational approaches.
‘Irrational’ protein design using directed evolution methods relying on entirely random mutagenesis techniques has also had its successes, particularly in cases in which sequential rounds of mutagenesis have been pursued.

According to "Drugs: From Discovery to Approval" by Rick Ng. The "rationality" of drug design refers to whether structure is used to inform the design.
The Irrational approach:
involves empirical observations of the pharmacological effects from
screening of many chemical compounds, mainly those from natural
products. The active component that gives rise to the observed effects
is isolated. The chemical formula is determined, and modifications are
made to improve its properties.
Whereas the Rational approach:
Requires three-dimensional knowledge of the target structure
involved in the disease. Drugs are designed to interact with this
target structure to create a beneficial response.

"Irrational" design in these papers refers to combinatorial mutagenesis, which is put forward as the alternative to "rational" protein design.
Rational design involves using existing information about a protein to choose residues to mutate.
From Nixon et al.:
